Kemoy Walker said: “My family feels happy that justice is being served, although it won’t bring Prince back, we are happy to hear a good outcome.”

He said the case was a “good example of the system working well”.

Mr Walker, a youth worker, has long campaigned in Moss Side to support and engage young people and steer them away from knife crime.

He said he understood that many others affected by knives had not received “justice in their families, so my heart goes out to them”.

“Talking to other youth workers, there needs to be a strategy to tackle knife crime that is local to Manchester and run by local people,” he added.

Mr Walker said there needed to be a “big conversation” about the “big crisis” in knife crime among young people.

“We have to deal with it, it’s too much to blame the system and everyone else.”

His comments come after more than 90 weapons, including knives and a machete, were seized by Greater Manchester Police from schools across the region in the last academic year.
