Following their cruel 'what are you crying about' jibe, he said, four officers drove him away from the hotel in a jeep. "Further up the road they pulled in at the side of road and a couple of the policemen got out and went to a fast food thing and got themselves something to eat."
Mr McAreavey said he was then taken to a derelict-looking building where he was put in a room and officers took off his shirt and examined him for marks. "I could see what was going through their minds," he said. "They put handcuffs on me and I was sat down on a bench."
Mr McAreavey said he was then left alone. "It was for at least five hours, I'm sure, more - actually it was late into the night."
He said he was eventually released after making a statement and returned to the hotel where a nurse cared for him through the night.
As he began giving evidence, Mr McAreavey described his "special" wife, the daughter of Mickey Harte, manager of the Tyrone Gaelic Football team. He produced pictures of her which were passed to the jury.
"Michaela was a wonderful, wonderful person, a really special human," he said. "She completed my whole life.
"She was loved by her parents - she was their only daughter. She was cherished by her brothers - their only sister. She had so many special qualities that it would be impossible for me to fully explain how a good a person she was."
Room attendant Avinash Treebhoowoon, 31, and floor supervisor Sandip Moneea, 42, deny the premeditated murder of teacher Mrs McAreavey at the Legends Hotel in January last year.
She had surprised them when she returned to the room to get biscuits. They claim she died accidentally when they pinned her down to stop her screaming. Mr McAreavey said he tried to revive his bride using CPR, although he did not know how to do it.
"Michaela was cold and her lips were blue. I just kept on saying, "Michaela, Michaela, wake up, come on, come on.
"I could see a mark on her neck. I didn't know what was going on."
The trial continues.
