A 16-year-old boy and 20-year-old man have been released on bail after a good Samaritan was reportedly threatened with a knife in Ipswich.

Police have said they were called to St Stephen’s Church Lane to reports that a man had a knife brandished at him after he challenged two people about their conduct towards a vulnerable male.

It is understood the vulnerable young man was said to have been taunted by the pair.

The two suspects then ran up away up Dial Lane and into Tower Street, pursued by the victim.

Two people were arrested a short while later in Fonnereau Road.

The incident occurred at 5.35pm on Wednesday, March 1.

A 20-year-old from Ipswich was detained on suspicion of causing fear/provocation of violence, while the 16-year-old boy from Ipswich was arrested on suspicion of possession of a bladed article in a public place.
