Sky TV's Sweetpea scenes shot by River Colne in Oxhey Park

Eagle-eyed viewers watching Sky TV's Sweetpea, starring Ella Purnell, may have noticed a familiar park show up on their screens.

Oxhey Park was used for scenes shot along the footpath by the River Colne.

• Slow Horses car-bombing scene filmed at West Herts College
• Crowd of kids flock to town centre as KSI spotted
• Filming spotted at Watford's former police station

Watford Borough Council has confirmed that the use of the park was agreed through the council-funded Hertfordshire Film Office.

It was produced by See-Saw Films, the production company that was also behind Slow Horses and Heartstopper.

Oxhey Park is one of Watford’s 17 Green Flag Award-accredited parks - the most in Hertfordshire.
