A teenager who was arrested for possessing a hammer after armed police were called to Ipswich’s waterfront to tackle a fight involving up to 14 people on Friday has been bailed.

Nearby offices and buildings were reportedly in lock-down amid concerns knives were being used in the brawl in Bath Street.

Officers and a dog unit were also called to the scene shortly after 1.30pm.

On Friday night, police confirmed that at least one arrest has been made. A 17-year-old boy was arrested for being in possession of a hammer.

He has now been bailed until November 3.

Earlier, an office worker at the scene, who wished to remain anonymous, said: “I was in the cafeteria and we were told to lock the office.

“It was worrying. At first we thought it was a bit of a prank, but when we realised it was actually happening it was quite scary.

“The police have dealt with it very promptly.”

According to reports, the groups involved in the fight were seen running around the area between Felaw Street and Bath Street.

In a short statement released earlier on Friday, a spokesman for Suffolk Constabulary said: “Police were called at 1.35pm today after a fight broke out in Ipswich town centre on Bath Street between approximately eight to 14 people.

“Several police units attended the incident, including a police dog. Police continued to patrol the area for some time afterwards to ensure that order remained.”
