Skip owner questioned over waste and money laundering
The boss of a skip hire firm has been arrested following the discovery of asbestos, toxic waste and other material dumped illegally in the hills above Belfast.
It is understood that a series of inspections found the material in amongst tons of building rubble.
The dumping is believed to have started a number of years ago.
The Northern Ireland Environment Agency launched the joint operation with the PSNI.
It said one man has been arrested for alleged waste, money laundering and criminal damages offences.
BBC Northern Ireland's Environment Correspondent Mike McKimm said: "Over the past few years there have been many complaints about the illegal dumping of waste, especially construction and building material in the hills above Ligoniel at the edge of North Belfast."
The NIEA's said the arrest forms part of one of the most significant investigations carried out to date by its crime unit.
