Harrowing images showing "police tape and blood stains" have emerged following a "serious assault" in South Harrow during the early hours of Saturday morning (October 14).
Officers from the Metropolitan Police were called to Northolt Road at the junction with Parkfield Road, near South Harrow railway station, at around 12.50am.
But officers were pictured at the scene come day break as forensic teams swung into action, with the bloody aftermath of the incident clearly visible in the road.
Police were joined by ambulance crews at the scene and later confirmed a 53-year-old man had suffered head injuries following an assault.
A suspect was arrested at the scene on suspicion of causing grievous bodily harm, the Met Police said.
The victim was taken to hospital and is currently undergoing medical checks, a police spokesman added.
According to the Met, investigations were ongoing at the scene into daylight hours when a forensic team arrived to analyse the blood stains.
Members of the public took to Twitter on Saturday morning to describe what they had witnessed at the scene.
Kuha Kumaran said: "Yet another crime scene on Northolt Road in South Harrow station. Why can't Harrow council install CCTV and send a tough message?"
Another said: "Same place in South Harrow, police tape and blood stains."
The Met spokesman added the force was awaiting an update on the man's condition.
Anyone with information is asked to call the Metropolitan Police on 101 or call Crimestoppers charity anonymously on 0800 555 111.
