SECURITY has been stepped up at a depot after thieves stole more than �11,000 of equipment in two separate break-ins.

Lawn mowers and barrels of fuel were among the items stolen from the headquarters of Serco, Welwyn Hatfield Council’s street scene partner, during two raids at the end of last year.

On both occasions, the thieves gained access through the roof of the depot, in Tewin Road, WGC.

The break-ins were revealed during Serco’s third quarterly report to Welwyn Hatfield Council, and discussed at its environment committee on March 11.

A Serco spokesman said: “We can confirm our depot workshop at Tewin Road was broken into twice towards the end of last year.

“On both occasions access was gained via the roof of the workshop and some landscaping and grounds maintenance tools and spares were taken.”

The company has now invested in a hi-tech security system to deter future burglars.

“At no time were services disrupted and since then Serco has invested in enhanced light-beam security systems throughout the depot site,” the spokesman added.
