Two Police Community Support Officers required hospital treatment after a brick was thrown through the window of their unmarked police car.
It happened at around 6:20pm on Sunday 9th April on Bolton Road while on patrol in the Eccleshill and Undercliffe area of Bradford.
One of the officers suffered injuries to his shoulder and hand and a female officer suffered injuries to her neck and head.
They have since been discharged from hospital and our recovering from their injuries.
A 15-year-old male has been arrested on suspicion of assaulting an emergency worker and remains in Police custody at this time.
Superintendent Richard Padwell of Bradford District Police said; “Assaults on emergency workers are completely unacceptable and we will not tolerate this kind of behaviour.
“These PCSOs were going about their daily duties, and they should not come under attack like this.
“This incident will be fully investigated by my officers.
“Both PCSOs are being fully supported by the force in what has clearly been a distressing time for them.”
