A man has been arrested after a teenage boy was inappropriately touched as he walked towards a train station.

The 15-year-old boy was walking near Oxhey Park when he was approached by a man at around 9pm on June 27.

He walked with the victim to Bushey train station entrance from Eastbury Road and attempted to talk to the boy.

Once they reached the train station the man touched the victim inappropriately.

A 19-year-old man from Edmonton was arrested at Watford Police Station last night.

He has been released on police bail until October 12 pending further inquiries.

CCTV footage of the attack was played on Monday night's BBC1 episode of Crimewatch.
