Some discarded trolleys have been found as far away as the Woodloes estate and the northern edge of Warwick.

Coun Glenn Williams has called for customers to return them and for the supermarket to make them harder to steal.

Coun Williams (Con, Warwick North) began noticing the errant trolleys when he began walking to work from his home in Kirby Road in February.

He said: "I have seen them at the bottom and top of Greville Road, opposite the doctor's surgery in Emscote Road, one outside the Marks and Spencers garage in Coventry Road, beside the canal in the Woodloes Estate and in Portobello Road.

"Customers are obviously taking trolleys and not bringing them back. It is very scruffy and irresponsible.

"It is not the sort of impression you want to give to anybody, residents or tourists."

Coun Williams believes Tesco should install measures to prevent the trolleys being taken outside the car park such as coin operated locks or a radio-activated braking systems at the car park exits.

Other members agreed. Council leader Coun Gerry Guest said he had seen supermarket staff returning to the store having collected a "lorry load" from around the town, and councillors voted to write to the store asking them to consider installing theft prevention measures.

A Tesco spokesman said the store was due for a refit in 2009 and was considering security measures for trolleys.

She added: "The store is aware this is a problem. They have a number of staff collecting trolleys from the car park and surrounding areas.

"It is as much of an inconvenience to Tesco as it is to customers and people living in the surrounding area."
