Officers believe they have located one of the two bodies still missing following the Didcot power station collapse.
Last month, the body of Christopher Huxtable, 34, a father-of-one from Swansea, was identified after being pulled from the wreckage - more than six months since the initial collapse.
On Wednesday, Thames Valley Police said they believed another body had been discovered.
The families of the missing men, Ken Cresswell, 57, and John Shaw, 61, both from Rotherham, have been informed, officers said.
The person is yet to be formally identified.
"Our thoughts remain with the families of Ken Cresswell and John Shaw and we would ask that their privacy is respected during this incredibly difficult time", a police spokesperson said.
