CCTV cameras at London City Airport’s DLR station failed to catch those responsible for a spate of vandalism.

Yobs launched a series of “sustained” attacks on the transport interchange late last year, repeatedly smashing panes of glass.

But they cannot be prosecuted because they were not picked up on the station’s CCTV, according to a report to Newham Council’s public transport liaison committee.

The report reads: “The CCTV was not able to capture the youths, only the acts of vandalism.

“This meant that the youths could not be arrested or prosecuted.”

Though the glass panels targeted are laminated and do not shatter, they look unsightly and are expensive to replace.

Safer Neighbourhood Teams and British Transport Police have since stepped up patrols in the area and distributed leaflets to neighbouring homes and businesses.

Newham Council is also investigating the possibility of investing in mobile CCTV for the area and transport chiefs are investigating the installation of a physical barrier to prevent further acts of vandalism.

There have been no further incidents since last year’s attacks, the report adds.
