Emmerdale star Asan N'Jie has been sacked by the ITV soap following what he admits was "unacceptable behaviour" at the TV Choice Awards.
The actor is reported to have attacked Hollyoaks star Jamie Lomas at the glitzy awards ceremony.
ITV announced in a statement: "Emmerdale suspended Asan N'Jie yesterday pending further investigation into an incident at a central London hotel on Monday night.
"ITV executives have met with him this morning and as a consequence Asan's contract has been terminated with immediate effect."
N'Jie said in a statement that he wanted "to learn" from his actions. "My behaviour at the TV Choice Awards was completely unacceptable and very much out of character," he said.
"I sincerely apologise to everybody who has been affected especially Jamie Lomas, the whole Emmerdale team, our audience, ITV, my family, and the organisers of the TV Choice Awards.
"I am devastated, accept full responsibility for my actions and I am determined to learn from this."
N'jie is reported to have sworn and thrown punches at 44-year-old Lomas following the ceremony on Monday at the Hilton Park Lane in Mayfair, London.
N'jie, who had been nominated for the best newcomer gong, was ejected from the event by security staff following the incident.
N'jie was nominated for a story-line in which his character Ellis Chapman was stabbed, but lost out to EastEnders' Kara-Leah Fernandes.
Hollyoaks star Lomas played village villain Warren Fox on and off for more than a decade in the Channel 4 soap.
