TMZ said Medina was arrested Saturday afternoon and will remain in jail until he posts his $1 million bail in connection with the death of Joshua Sutter.
Medina reportedly said he tried to walk away from the confrontation and retreated to his bedroom with his girlfriend, but admitted he stabbed Sutter once in the abdomen when Sutter forced his way into the room.
The 37-year-old actor called 911 and waited for police to arrive after which he was arrested and booked on suspicion of murder, TMZ said.
