A police officer who suffered serious head injuries while responding to an emergency call is said to be recovering well.
The Home Secretary described the assault on the officer in Scunthorpe, Lincolnshire, as "shocking and senseless".
Humberside Police said the officer, who was taken to hospital on Friday, is in a non-life threatening condition and is recovering well.
The force previously said he was being treated for serious injuries in hospital after an assault reported at an education premises in Scunthorpe at 2.40pm on Friday.
