“A cordon on Leverton Drive has now been removed and we are still working to establish the exact location of the incident in which the 17-year-old boy was injured.
“Throughout today and into the evening local residents can expect to see an increased presence as officers speak to potential witnesses and I’d urge anyone who either saw what happened, or who has information about either of the incidents, to contact us.
“We need to identify those involved and as the investigations continue at pace, I’d like to ask people within the area who may have information but have not yet been in touch to speak to us. Please either talk to an officer in the area or call 101 quoting incident number 748 of 4 February 2020.
