A 16-year-old boy arrested after armed police were called to reports of three people being threatened with a gun has been released from custody.
Officers were dispatched to Grove Lane, Ipswich, at about 17:00 BST on Tuesday to reports that five men, including two with guns, had entered a house.
They had threatened two women and a man in the house, police said.
A boy was later arrested on suspicion of possession of a firearm with intent to cause fear.
He has now been released under investigation pending further inquiries.
While detectives believe this was a targeted incident, witnesses or anyone with information is urged to contact Suffolk Police.
