Police are appealing for information after an officer was assaulted in Cheetham Hill.
Shortly after 6.50pm on Friday 22nd December, police were called to reports of a fight on Smedley Lane Playing Fields, off Cardinal Street.
Officers attended and found a large group of youths who subsequently fled from the park.
A search of the area commenced during which an officer was hit over the back of the head and left unconscious.
The officer was taken to hospital where he received treatment for his injuries.
It is completely unacceptable that an officer responding to an incident has been assaulted.
