A hooded man was caught on CCTV hitting a pet pony about the head after sneaking into its stable.
Lenny the 11-year-old pony was slapped and ridden by the mystery man, who entered his stables in Midgeland Road, Marton, in the early hours of Wednesday.
But police said they are no longer looking into the incident, which owner Liz Jackson, 47, said left the Welsh pony 'traumatised'.
She said: “I’m devastated.
“When I came down on the morning the front of my yard was open. That prompted me to look at my CCTV, and needless to say I was horrified by what I saw."
CCTV footage shared online showed a big man sitting on Lenny and hitting him several times about the head.
Further clips appeared to show the man struggling with Lenny as he led him into a field.
She said: “I got him thoroughly checked over and I just think he’s a bit traumatised.
“I think (the man) has been before because he’s so blase and he’s made a beeline for the smallest pony on the yard.
“I’m totally distraught and I’m very worried that he’s going to come up again and there’s nothing I can do.
“I’m just hoping that if we get the footage out there, somebody will be able to identify him.”
A police spokesman said: "We got a call around 10am yesterday to reports of a burglary on Midgeland Road, Blackpool. It happened around 1.30am. A man has entered the stables and has been riding around on a pony.
"While the man can be seen the be riding the pony there's no evidence that an offence has been committed. While he has entered the stables there has been no burglary, no theft. There has not been any damage to the pony or stables."
He said no further police action would be taken.
