A man has been charged with grievous bodily harm and assault after three police officers were attacked in north-west London while helping an elderly man.
George Agbapuruonwu, 36, was charged with the offences over the alleged incident, according to Scotland Yard.
The skirmish, which took place on Monday night (January 8) left one of the officers with a fractured eye socket.
At approximately 11pm on Monday January 8, the officers responded to requests for assistance after a man collapsed on a bus. As the officers were helping the man and his grandson in Alexandra Avenue, at the junction with Eastcote Lane in Harrow they were approached by a man.
Without provocation the man physically assaulted the Sergeant and two police constables, kicking and punching them. The most seriously injured officer, a male police constable, was taken to hospital suffering from a fractured eye socket.
The two others were not seriously injured.
The three officers were able to arrest the 36-year-old man on suspicion of GBH and assault on police officers. He remains in custody at a west London police station.
Chief Inspector Alison Darke, from Harrow Police, said:
"Whilst helping an elderly man and his grandson three of our officers were subjected to a vicious and unprovoked attack which has resulted in one of them being hospitalised overnight.
"Policing is by its very nature unpredictable - however no officer should be subject to such a violent attack."
