A 45-year-old man arrested on suspicion of false imprisonment after a woman was killed on a railway line near Brandon was last night (Tuesday) released on bail.

It is thought the young woman, who was struck by a train Monday evening, had been involved in a 'domestic incident' on a boat in the lead-up to her death.

Her concerned family called the police at 8.30pm on Monday, but she was hit by a freight train at a level crossing at Santon Downham just an hour later.

Paramedics were called, but the woman was pronounced dead at the scene.

At the time, Suffolk Police had been making 'active inquiries' about a 'domestic incident on a boat on the River Little Ouse'.

British Transport Police and Suffolk Constabulary launched a joint investigation and a 45-year-old man from Brandon was arrested in the early hours of Tuesday on suspicion of false imprisonment.

He was questioned before being released on police bail and must return to Bury St Edmunds police station on April 26.

A post mortem examination confirmed the young woman had died as a result of being struck by a train and her death is not being treated as suspicious.

Suffolk police would now like to talk to another woman who is believed to have been on the same boat as the victim on Monday afternoon.

She was described as in her late 50s or early 60s with grey or blonde hair. She was wearing a lilac jacket and had a purple mountain bike with her at the moorings.

She is thought to have boarded the boat, spoken to the occupants and taken a ride along the river.

Anyone who may have seen a woman in distress in the forest around Santon Downham before 9.30pm is asked to call West Suffolk CID on 01473 613500.
