Two people have died in a crash with a coach following a police pursuit in west London.
The Metropolitan Police said officers responded to reports of an aggravated burglary in Harrow, north-west London, at about 8.40pm on Sunday.
As part of the response, a pursuit began, with a police helicopter also called to assist.
At about 9pm, the vehicle being pursued moved on to the wrong side of the carriageway on the A40 and crashed with a coach near the junction of Kingsdown Avenue, Acton.
A male and a female were pronounced dead at the scene, while a second man was taken to hospital for treatment. All three were occupants of the vehicle being pursued.
There were no reports of any other serious injuries and details of the number of people on the coach have not been released.
The Met said the police cars did not follow when the vehicle drove on to the wrong side of the road.
Road closures remain in place in the area, and London Ambulance Service and London Fire Brigade are on the scene.
Scotland Yard said the Directorate of Professional Standards and the Independent Office for Police Conduct (IOPC) had been informed of the incident.
Last month, the IOPC said fatalities and serious injuries following pursuits were “thankfully rare” as it investigated four separate fatal incidents involving patrol cars across the country over the course of a week.
PCSO Holly Burke was fatally injured by an alleged hit-and-run driver who struck her car while being chased by police in the West Midlands on January 22, while a 26-year-old refugee from Eritrea died after being hit by a police car responding to a 999 call in east London on the same day.
Jessie Whitehead, 74, was riding a mobility scooter when she was hit by a marked squad car as it responded to an emergency in Bedworth, Warwickshire, and Paul Radcliffe, 18, was killed by a car which had failed to stop for police in Oadby, Leicestershire, on January 19.
