Disgraced All Black Zac Guildford was seen handcuffed in a Rarotonga police station after his drunken episode at Trader Jacks bar.
A police source told the Herald in the Cook Islands capital late last night that Guildford said, ``I'm sorry'', when he saw him at the station.
The source said Guildford could still face charges.
Earlier, Guildford had tried to escape from police who were taking him to hospital to be treated for injuries he got while swimming through a lagoon.
He was still naked at that time.
Friends brought clothes for him from his hotel room to the police station.
Trader Jacks owner Jack Cooper said Guildford was ``completely out of it'' when he entered the bar.
``He went up and punched one of our patrons and then went round the bar and then he struck a guy who was celebrating his 60th birthday.
``Then he realised he was naked and started apologising to everyone.''
The 60-year-old allegedly struck was Australian Nick Cox.
Mr Cox told the Herald on Sunday he did not plan to lay a formal complaint, but Guildford had ``an issue that he needs to sort out''.
