An investigation is under way after human remains were discovered at a waste recycling plant in Dublin.

A leg was discovered by an employee at the Thorntons Recycling Centre on the Killeen Road in Ballyfermot at around 11.40pm.

The leg was found among the waste material.

Work at the plant was stopped and the equipment was shut down.

A doctor was called and confirmed the limb was human.

A thigh was subsequently found and a search of the plant is continuing.

Deputy State Pathologist Dr Michael Curtis is to examine the human remains.

A large section of the recycling centre has now been sealed off as gardaí carry out a forensic examination.

Gardaí are keeping an open mind on the discovery of the remains.

While it could be sinister, they say there is also a possibility that it could be misplaced medical waste.
