A regional radio executive has been stood down after groping an employee in front of a live audience at the Australian Audio Awards.

Guy Ashford, the boss of Newcastle radio station 2HD, was on stage at Carriageworks in Sydney on Thursday night when he hugged award winner Cheralyn Darcey, then grabbed her on the backside with his left hand.

He then threw his arms into the air as the crowd gasped.

Darcey, who works for Ashford as a radio host, received her award for best newcomer.

'All right...' one of the award night hosts said.
