Two men from Rotherham have been identified as missing after the collapse of a power station being prepared for demolition.
One worker was killed and three are still missing after the incident last month at Didcot in Oxfordshire.
Thames Valley Police said in a statement: "The family of Ken Cresswell, aged 57, from Rotherham, confirmed that their loved one is missing following the partial collapse of Didcot A Power Station on 23 February.
"Ken is loved very much and his family haven't given up hope of him being recovered and returned home. They ask the media to continue to respect their privacy at this difficult time.
"The family of John Shaw, aged 61, from Rotherham, confirmed that their loved one is missing. John is loved very much and his family haven't given up hope of him being recovered and returned home. They ask the media to continue to respect their privacy at this difficult time."
Police today met today with the families of the three missing people, as part of the ongoing support being given.
"Our priority remains the recovery of their loved ones so they can be returned to their families and to understand what caused this incident," said a statement.
The power station is owned by Npower.
Mike Collings, 53, was killed when the structure folded nearly two weeks ago.
Emergency services have since said it is "highly unlikely" the missing are still alive and last week stated that the recovery operation could take months.
The third demolition worker buried and left unaccounted for has been named by his family as Chris Huxtable.
His partner Jade Ali has launched a petition in a bid to find the missing men.
Ms Ali, from Swansea, posted: "We need them home. Minutes are turning into hours, and days are turning into weeks.
"Get these three hard working men out and back home."
The petition has gathered more than 1,200 signatures so far.
