"Furthermore, it is inevitable parents across Ipswich may also be anxious following this morning's incident.

"I would reassure the public that our priority is to keep everyone safe and incidents such as this are extremely rare in Suffolk."

The teenager was arrested on suspicion of attempted murder shortly before 11:00 and is in custody at Suffolk police headquarters at Martlesham.

Assistant Chief Constable Rob Jones said he believed "there is nothing to suggest there is wider threat to the public".

Phil Bennett, 38, of East Bergholt, told the PA news agency that his father lives near to the scene in Kesgrave and heard a gunshot.

"He's a retired paramedic - he's heard a lot of gunshots in his time, so he stayed indoors," he said.

"The next thing he knew there were police piling in, then it's a scene of crime.

"It's hard to believe this has happened 100m (328ft) from my mum's front door, that someone's been shot. It's terrible what's going on."

Local resident Andy Watts told BBC Look East he was walking his dog near the area and "heard a gunshot and then I heard a great big scream".

"That's all I can say. It was a quick as that. It sounded like scaffolding falling down originally because it was a big, big crash," he said.

"I saw them working on the young lad over on the green, he was over there for quite a while, while they were attending to him, a lot of ambulance staff and paramedics working on him."
