“This appears to have been a deliberate attempt to kill police,” said Mr Lunn.
“This type of attack achieves nothing except putting police officers, who are trying to protect the local community, in danger and diverting vital resources from other areas that might need them.
“There is no justification for this attack. Any act of violence against police is an assault on the rule of law and everyone in our society.
“I urge anyone with information to contact police with it immediately.”
