An 18-year-old refugee is facing the second day of trial accused of planting a bomb on a District Line train, which partially exploded at Parsons Green station in September 2017.

Ahmed Hassan Mohammed Ali was living by foster carers in Cavendish Road, Sunbury, and denies charges of attempted murder and using the chemical compound TATP to cause an explosion likely to endanger life .

The Old Bailey heard how the improvised explosive device was allegedly planted on the train by Ali, who left just two minutes before it detonated on September 15, injuring 29 people.

Immigration officials were told by the refugee from Iraq that he had received ISIS training, the court heard on the first day of the trial on Wednesday (March 7).

Statements from witnesses

Several of the witnesses who testified today, all of whom were on board the train when the bomb exploded, were audibly sobbing when retelling their accounts of the day.

The witnesses included a serving army officer who went back on the train after it had emptied and photographed the smoking paint bucket from several angles.

I suspected it was an IED (Improvised Explosive Device) in a carrier bag, a plastic bag, and the top of it was burning and there were wires coming out of it.

I decided to get a closer examination of it so I opened the doors, took a breath and went in.

The witness was able to help the specialist officers who arrived at the scene and was thanked by the judge, Justice Haddon-Cave for his bravery dealing with the events of the day.

Retired policeman's actions

On board the train was a former Counter Terrorism Met officer who had retired a month earlier.

He described to the jury how his experience of the explosion.

I saw a rolling fireball come over the ceiling, wall to wall, slowly coming up.

At that point I looked towards the fireball and everything happened in slow motion.

The retired officer came out of the carriage, clipping his arm on the doors which were closing.

He knew there was only one set of stairs and decided not to get stuck at the exit, instead calling 999 and asking for all the services

I was checking for potential fatalities and saw debris like handbags on the ground.

I saw the device through the doors, I saw a large white paint tub in a Lidl bag.

There was clothing on top that was alight and there were flames about six inches high still.

Woman's hair immediately caught fire

Another witness has told of how she saw a man get hit with a “wall of glass” into the back of his head seconds after the explosion.

She described hearing a loud cracking noise followed by a bang.

The witness was thrown on to the floor as flames passed over her body.

She told the court she had just curled her hair that morning and applied hairspray.

My hair immediately caught fire as I lay on the ground.

Witness's fell to her knees, on fire

Miss S boarded the train at Southfields and was in the carriage at Parsons Green, where she was badly injured.

I jumped from the carriage and probably landed on my knees. I fell into the trench and people helped me up.

Miss S’s coat was on fire when she bomb exploded and sustained burns to her face, hair, legs and hands.

The explosion

The jury are being shown several camera angles from on board the train, pulling up to Parsons Green station at 8.19am.

Commuters are getting on the station when there is an explosion, “very close to the camera”.

Passengers can be seen rushing out of the station, scrambling to gather their belongings.

At this point there is still smoking on the ground.

CCTV from the platform shows a fireball coming out of the trains doors, followed by a rush of people out of the rear of the train towards the stairs.

Seconds later the entire train appears to empty and people try to get down the stair and out of the station.

What happened on that District line train

Hassan walks through the carriage before placing the bag on the floor before moving slightly away.

He remained near to it, in that vicinity until Putney Bridge station.

This can be seen on CCTV footage from inside the busy train.

The journey ends for him at 08.17 am when he leaves the train.

The bag cannot be seen on Hassan in CCTV images inside the station.

He leaves the station, tapping out on a “cash card”.

Hassan then goes to a cash point at 8.19 am and withdraws £200 in cash.

The court is now shown a laser scan of Parsons Green station and the district line train showing the location of the exploded device.

In the same location as we have seen the device left by Mr Hassan.

The device was in the rear of the train in the penultimate carriage.

Further CCTV footage

A laser-photgraphed reconstruction of Wimbledon station shows Hassans route through the station, to the toilets where he is alleged to have set the timer.

All available CCTV footage has been examined and it does not appear as through Hassan put his hand in the bag until that point.

He enters the toilet at 7.57 am and remains there for 13 minutes.

CCTV shows him emerging from the toilet, bag in hand and making his was to the DIstrict line platform, boarding an eastbound District line train bound for Edgware Road.

From Asda, Hassan purchased:

  • Chicken
  • Matches
  • Batteries
