A man who suffered a serious head injury after he collapsed on a residential street is in a critical condition, police have confirmed.

The 45-year-old was found on Wolseley Road, Wealdstone, in the early hours of September 24 where he was attended to by Metropolitan Police officers and the London Ambulance Service.

He was taken to a central London hospital where he remains in a critical but stable condition. His next of kin have been informed.

Police had earlier described the incident as a “serious assault” but enquiries into how he sustained the injuries are ongoing.
