A SUSPECTED body uncovered by workmen sparked a police investigation.

Workmen found a large object covered in plastic sheeting in a deep concrete holding tank off the A41 Bicester bypass.

Fearing it contained a human body, they called police.

Officers attended the scene just before 4pm yesterday.

And they then called in specialist investigators because the contents within the plastic sheeting, which was submerged in water, could not be easily established.

The A41 between Rodney House roundabout and the Esso roundabout was closed during the incident.

A police spokesman said: "The plastic sheeting was subsequently found to contain only mud and waste."
