Police have revealed that a second horse became trapped in a cattle grid during a travellers' event in the New Forest.

It was freed unhurt following an earlier incident in which another equine broke its leg in two places and had to be put down.

People from across the UK converged on the Forest to take part in the Tracy Cooper Drive, which took place on August 10-11.

As reported in the Daily Echo, Balmer Lawn in Brockenhurst was littered with tacks and broken glass - apparently in an attempt to sabotage the event.

Now Hampshire's Police and Crime Commissioner, Donna Jones, has vowed that concerns about the two-day event will be fully investigated.

She said: "The ride-out caused a traffic backlog in an already busy seasonal area and it is so sad that a horse had to be put down.

"I have been in contact with the local policing team in the New Forest to make sure the incidents are being thoroughly looked into. Every measure is being taken to review and investigate the incidents."

A statement on the New Forest Heart Police Facebook page added: "We are aware of concerns raised following the pony and trap ride-out.

"Officers spoke to many members of the public over the weekend, some of whom raised concerns around animal welfare.

"It follows an incident whereby we took control of a horse which had suffered a broken leg at Ashurst. There was a further report of a horse having been caught in a cattle grid. Fortunately it was freed and uninjured."

The statement also referred to the objects scattered at Balmer Lawn.

"Officers worked to clear the ground and direct the passage of the animals to ensure their welfare. There were a number of items present at the site, including nails and broken glass, which were removed."

Meanwhile, Mrs Jones has held talks with New Forest councillors.

Her spokesperson said: "It was agreed that all partners would continue to share information and intelligence, work together to share any concerns and make sure everyone is fully prepared for these events in the future."

Ms Cooper has said the Ashurst incident did not take place during the drive itself.

Referring to the person in charge of the horse she said: "He had never been down to the New Forest before and didn’t know the roads very well.

"He took his eyes off the road for a second to ask the person following him a question, and when he turned back it was a matter of it being too late."
