AN investigation is continuing after a worker was seriously injured in an accident at a Teesside steel plant.

The 54-year-old engineer, who has not been named, sustained serious head, chest and foot injuries on Tuesday evening, when he was crushed between a metal plate and a conveyor, at the Corus Tubes and Pipes works, at Portrack Lane, Stockton.

His colleagues managed to lift the massive metal plate off the man before the fire brigade and ambulance crew arrived at the Corus 84ins pipe mill.

Health and Safety Executive (HSE) officials are looking into the incident and an internal investigation has also been launched.

The man, who has been working for Corus for 11 years, is believed to have been supervising a test on a conveyor belt when the accident happened.

It is thought he had been part of a team carrying out maintenance on the machine.

Three fire crews attended the scene, as well as the emergency tender and hydraulic platform.

The man was taken to Middlesbrough General Hospital, where his condition was described as "poorly but stable".

An HSE spokesman said: "The investigation is at an early stage, but we think it involves a plate conveyor on a series of rollers and somehow this employee has had a fall and ended up with multiple injuries."

A Corus spokesman confirmed the details of the incident and said an investigation was under way
