Workers at a town centre clinic were left disgusted and baffled after a ‘bizarre’ paint attack by vandals.

Offenders left Trojan Physiotherapy Group clinic in Accrington splattered in green paint  before leaving the tin and a pair of blood-stained shoes at the scene.

Police forensic teams have visited the premises and bosses hope they will catch the perpetrators using DNA from the shoes.

Neighbours on Burnley Road heard two men and a woman arguing outside the shop at the time of the incident and another neighbour called the clinic owners after later discovering the paint damage.

Leigh Cain, managing assistant, said they have no idea who is responsible and said it was ‘bizarre’ for the offenders to leave evidence linking them to the crime.

She said: “They left a paint tin and a pair of nice women’s going out shoes. They might have gone out for a drink and on the way home somehow decided to chuck the paint over the shop.

“What normal person would leave the paint tin and the shoes at the scene of the crime? It seems a bit bizarre and doesn’t make sense.

“There was a tiny bit of blood on the shoe and we are hoping the police can get something from that and also the sweat from the shoe.

“Everybody here is disgusted and doesn’t know why anyone would target Trojan.

“We think it must have been targeted but if not why would they want to chuck paint over the shop?”

Clinic staff said there was no other damage and hope the green emulsion paint can be cleaned off.

Owner Julie Quinn, who took over the clinic earlier this year, said she was shocked by the incident.

She said: “We don’t know who is responsible and it’s something that has just came out right out of the blue. Obviously there’s going to be costs incurred and hopefully if they catch whoever did this that bill can be passed on to them.”

A police spokesperson said the incident is believed to have taken place between 6am and 7am on Sunday, August 11 and local CCTV is being investigated.

She said: “Somebody has approached the business premises and thrown a tin of paint over the front window and door and left the paint tin and a pair of shoes at the scene.

“Our enquiries our ongoing.”
