A teenage boy who was riding an electric bike has died after he was followed by police and then collided with a parked ambulance in Salford.
Greater Manchester Police (GMP) said traffic officers had followed the 15-year-old until their police vehicle’s path was blocked by bollards.
The boy then rode on and collided with a stationary ambulance with crew inside, North West Ambulance said.
The Independent Office for Police Conduct (IOPC) is investigating.
At about 14:00 BST, the boy was followed by police officers along Fitzwarren Street and onto Lower Seedley Road, where bollards blocked the police vehicle’s way.
He then collided with the ambulance parked in Langworthy Road.
Ambulance crew inside were able to treat him immediately before taking him to hospital where he later died, the North West Ambulance Trust said.
The mood near to the scene of the crash was sombre on Thursday evening, with the family of the boy understood to live nearby.
Flowers, candles and cards have been left at the scene beside a framed picture of the young boy.
One tribute attached to a bunch of roses read: “Doesn’t feel real writing this card. My heart is broken.”
Another said: “You will always have a special place in my heart, I love you loads my dude.”
Langworthy Road is a busy main road and would have had a lot of traffic on it at the time of the collision.
A police cordon in place there for much of the evening has now been lifted.
In a statement, GMP said the IOPC was now leading the investigation.
“Our thoughts are with the family and friends of the boy who tragically died,” it said.
The IOPC, which oversees police conduct, said it was “independently investigating the circumstances of a serious collision involving an e-bike and an ambulance in Salford”.
“Our thoughts are with his family and loved ones, as well as all those affected by this tragedy,” its spokesman said.
“We were notified by Greater Manchester Police due to the fact a police vehicle had been following the e-bike shortly before the collision.
“We have sent investigators to the scene of the collision, at the junction of Langworthy Road and Lower Seedley Road, as well as to the police post-incident procedures, to begin gathering evidence.”
He added the IOPC would provide “further details once we are in a position to do so”.
Last month, 15-year-old Harvey Evans and 16-year-old Kyrees Sullivan were killed in an e-bike collision in Cardiff after being followed by a police van. Their deaths sparked a riot in the area.
