About 40 people are being treated by medical personnel after a reported chemical leak at a holiday park swimming pool in east England, police said on Sunday.

Around 40 people have been taken to hospital to be treated for difficulties with breathing, the Norfolk Constabulary said, according to Xinhua.

Officers were called by Norfolk Fire and Rescue Service at around 2.30 p.m. on Sunday to reports of a chemical leak in the swimming pool at the Wild Duck Holiday Park in Belton near Great Yarmouth in east England's Norfolk county.

The immediate area was evacuated and a 20-metre cordon put in place.

Later in the afternoon, police confirmed that the swimming pool has been declared safe following the incident.
