NOTTING HILL detectives have launched a plea for witnesses after robbers attacked three friends outside a busy restaurant.

A 56-year-old man and a 57-year-old woman had just joined a pal after leaving Raoul's bar in Talbot Road at 7.45pm when a hooded man, described as being aged 25 and black, struck.

The mates were attacked from behind. The thug put his hands around the man's neck before smashing his glasses and breaking his kneecap.

The would-be robber, who was wearing a green top and grey jeans, tried to take the woman's handbag and earrings before fleeing east down Talbot Road.

The violent incident occurred outside the popular Ledbury restaurant on June 29, which was crammed with at least crowds enjoying the early evening sun.

After launching an investigating and viewing CCTV, cops are now appealing for diners who may have seen anything unusual.

Det Con Chris Arkell said: "This was a very nasty robbery and I would appeal to anyone who saw the incident to contact me with any details they may have, no matter how small.

"Immediately opposite where the robbery took place is the is the Ledbury restaurant which has an outside terrace where there were in excess of 30 people - any of whom may have seen the attack. A short distance further is another restaurant/bar, again in line of sight of the incident.

"There were a number of people who stopped immediately after the attack, but who didn't give any details. I would urge these people to contact me."
