Herts Police have explained why a helicopter was spotted hovering near Watford late at night.

Residents speculated there had been people on the railway line as they questioned online why the aircraft was circling over the Croxley Moors and Holywell in west Watford for over an hour late on Sunday, June 9.

A British Transport Police spokesperson confirmed today (June 11) that the helicopter was dispatched after they and Hertfordshire Police were called to reports of trespassing near Rickmansworth at around 10pm.

They confirmed that a 45-year-old man from Hillingdon was arrested on suspicion of trespass and released on conditional bail.

The charity will showcase the new helicopter at its Heli-bration event in the grounds of Hertfordshire stately home Hatfield House on Sunday, July 14.
