Officers are appealing for information following an assault in Wythenshawe in the early hours of Saturday.
At around 1:15am on Saturday 23 February 2018, two brothers, both aged in their 30s, and a 33-year-old woman were stood on Church Road, Northenden, when a large group of youths across the road started shouting abuse at the woman.
