Detectives are appealing for information after two teenagers were injured – one seriously – following an assault in Darwen.
Police were called by the Ambulance Service around 4.45pm on Sunday (January 8) following reports of an incident at the skate park off Olive Lane.
Officers attended and two boys aged 14 and 15 were found with serious injuries.
Police believe the pair had been attacked with a hockey stick by two males who then made off from the scene.
The 15-year-old boy suffered injuries to his mouth and teeth, while the 14-year-old boy was treated at Manchester Hospital for a fractured skull, head wound and broken arm.
Following enquiries two males aged 17 and 19 were later arrested by police.
Officers are continuing to investigate the circumstances around the assault and are urging anyone with information to come forward.
Temp Det Sgt Mark Hutchingson, of Blackburn CID, said: “This was a particularly vicious attack which left two teenagers injured, one seriously.
“While we have made two arrests as part of our enquiries, we are continuing to appeal to witnesses to come forward and assist with our investigation.
“The attack took place at a busy skate park and we believe several people will have seen what happened.
“Anyone with information is urged to call police immediately.”
Two males aged 17 and 19, both from Darwen, were arrested on suspicion of assault and bailed to March 10.
