A police helicopter was scrambled in the hunt for a man believed to have carried out a sex attack on a cow.

Officers launched a hunt for the suspect, who was reportedly seen "committing a sexual act" on the farm animal in Hertfordshire.

The man, in his mid-20s, had been spotted interfering with a cow near Denham Way, in Maple Cross, early on Saturday morning.

But despite the ground search and help of the police helicopter, the suspect was not found. Police are continuing to search for the man, who is believed to have carried out the attack at about 7am.

Inquiries are ongoing and witnesses are being sought.

A Hertfordshire Constabulary spokesman said: "Police were called at 7.18am to Denham Way in Maple Cross, to reports that a man was committing a sexual act on a cow.

"Officers attended and a search was conducted, which included the police helicopter however, no one was located.

"Enquires are on-going and anyone with information that could assist the investigation is asked to contact Hertfordshire Constabulary."

Police said the suspect is described as an Asian man in his mid-20s, around 6ft tall and of slim build.

He is reported to have short short hair and was wearing a shell type jacket, which looked old, in a faded green colour and dark coloured trousers.
