A vehicle full of cops that crashed in Harrow - leaving one seriously injured in hospital - was en route to a 999 gun incident, the Observer can reveal.
The police car, with three occupants, smashed into a lamp post on West Street, Harrow, and ended up in a field at 12.05am on Thursday January 15.
A Harrow police spokesman said: "The emergency call was a reported firearms incident in the Kenton area, which police attended to along with armed officers. No firearms were seen or discovered and no further action was required."
In the car smash, a man in his 20s suffered head injuries and was taken to Northwick Park Hospital, in Watford Road, Harrow, while another officer in his 40s was treated at the Royal Free Hospital, in Hampstead.
Borough commander Richard Walton said: "Following the incident on Thursday January 15, when three Harrow police officers were injured whilst responding to an emergency call, one officer remains in hospital.
"His condition is serious, but stable. We remain optimistic that he will make a full recovery in due course.
"The other two officers involved in the collision have been discharged from hospital and are recovering at home.
"We hope and trust that all three officers will recover fully in time and wish them all well. We will do all we can to give them the support they need."
The traffic division at Alperton has launched an investigation into the incident, which took place at the junction with Lower Road.
