A knifeman who stabbed a teenager in a Bearwood park is still at large.
One mother described seeing the ‘whole park screaming and running’ as the incident unfolded.
Police have now confirmed that no arrests had yet been made in connection with the violent assault.
A spokesman for the West Midlands force said it is believed the incident was a ‘targeted attack’, as patrols were stepped up in a bid to crackdown on anti-social behaviour in open spaces and parks.
At the time of the incident, they said: “As lockdown restrictions ease and the weather warms, there has been a rise in reports of crime and anti-social behaviour involving youths in open spaces and parks.
“It is understandably concerning for the public, but it is important to stress that we believe the incident last night was a targeted attack.
“Officers are working around the clock to identify and pursue the offenders involved.
“We have increased patrols around parks and open spaces and have officers looking at CCTV.
“We are also working with partner agencies, including environmental protection officers and youth workers, and are engaging with schools – including the school the victim attends – as part of our efforts to reduce knife crime.
“We have a dedicated Violence Reduction Unit which looks at preventative work and diversions for young people.”
