The London Borough of Bromley is offering a £500 reward for information after four trailers of dumped rubbish were abandoned on its streets.
Three 40ft trailers were abandoned in Copers Cope Road, Beckenham, and a fourth in nearby Worsley Bridge Road.
Bromley fears the costs of the specialist removal and disposal operation could exceed £80,000. The waste had been baled or wrapped in black plastic wrapping and left on the trailers, which are all in a poor state of repair.
The trailers’ weight is such that they have damaged the road surface and will require specialist recovery, especially as they are not roadworthy.
Officers are studying CCTV images to try to determine who was responsible. One potential clue is that an undriveable heavy goods vehicle cab has been found in Worsley Bridge Road.
The vehicle registration of the white MAN D20 cab is BX56 LSN, which is shown on the Driver and Vehicle Licensing Agency website as having been due to pay tax last September.
Kate Lymer, executive councillor for public protection and enforcement, said: “This deliberate act of fly-tipping is a form of organised crime.
“People are paying good money to these cynical criminals in the belief that they will dispose of their waste. But they end up dumping it instead and keeping the cash for themselves – which can amount to thousands of pounds.
“Bromley residents are left to foot the clean-up bill via their council tax through no fault of their own. We need your help to catch the perpetrators.”
