Detectives say they know there are witnesses who saw what happened, but are yet to come forward.
The park was open at the time of the shooting and residents suggest people would have been walking their dogs at the time.
One woman said her son was walking their dog when he heard “four pops” he later realised were gunshots.

Sinead Oldnall said: “My son was in the park when it happened last night.
“He phoned me at 7.20pm, he had just got home. He heard four pops and thought it was fireworks and then he realised that it wasn’t.
“And he was not far. He was literally just there [near the Green Lanes entrance, where a crime scene is in place] and he just ran home with the dog.
“He phoned me in a panic. He was shaken up.”
A woman, who preferred not to be named described Clissold Park as popular with picnics and families, with multiple playgrounds inside.
She said: “It worries me. I have a seven-year-old boy and this is so close to home.
“My son is talking about it, saying ‘Mum, what if it happens near us.’ He is worried.
“It could happen to anyone at any time. I heard all the sirens and the helicopter – it was crazy. What is this world coming to?”
