DETECTIVES investigating a serious sexual assault on a vulnerable woman in her 60s in York have arrested a man.

North Yorkshire Police said a man in his 30s was arrested this morning and was currently in police custody for questioning.

The assault happened near the riverside at the back of St Peter's School on Tuesday evening.

The victim was with a man at around 7pm near Lendal Bridge and then walked with him down the side of the River Ouse in the direction of Scarborough Bridge, passing the Esplanade car park and the Post Office building on her left hand side.

They then crossed over Scarborough Bridge and, once over the bridge, continued walking alongside the river, out of town towards the back of St Peter’s school and Clifton Bridge.

When they approached the back of the school, the man subjected the woman to a serious sexual and physical assault and stole money from her.
