TWISTED vandals are smearing excrement on CCTV vans owned by a crime-fighting council organisation.

Spy cam vans, which are branded with Community Safety Glasgow's logos, have been targeted while parked in areas across Glasgow.

Insiders said a "poo dunnit" investigation has been launched to find the mystery menaces, who have struck during recent weeks.

It is thought disgruntled members of the public - who may have been fined for dog fouling - are behind the vandalism.

Community Safety Glasgow officers can pursue owners if they fail to clean up the mess when out with their dog.

Fines for dog fouling start at £40 and rise to £60 if unpaid within 28 days.

Community Safety Glasgow said a man had been reported to police in connection with one alleged incident.

In a statement, the organisation said: "Unfortunately, the officers sometimes encounter abuse and aggression from members of the public.

"Most recently, our officers' CCTV vans have been targeted and the doors, and door handles, have been covered in excrement.

"This is not only extremely unpleasant and dangerous for the officers involved, but means the vehicles have to be returned to be cleaned, which reduces the amount of time the officers are in communities.

"We can confirm that the most recent incident was captured on CCTV, which has been provided to Police Scotland.

"The adult male who allegedly did this has now been identified. This matter is now being dealt with by Police Scotland

Community Safety Glasgow bosses said posts on social media - which incite acts to be carried out against wardens - have been spotted.

It is understood a number of posts on Facebook are being monitored.

The statement added: "Our officers receive a range of training to ensure they are professional and respectful and any complaints about their conduct are taken seriously.

"We ask that members of the public treat them with respect and continue to support us in helping to keep Glasgow safe."

Last year, we told how 20 Community Enforcement Officers underwent cycle patrol training to tackle antisocial behaviour, littering and dog fouling.

Council bosses introduced the new scheme after the number of dog owners fined for failing to clean up after their pets soared.

It came after the Evening Times revealed details of a new blitz against dog fouling.

Authorities warned that pooches could be removed and rehomed, if owners refuse to bin their mess.

Dog owners who don't clean up after their pet are one of the biggest irritations for the city's residents and thousands of people backed the clampdown.
