Lost actor Daniel Dae Kim has said he is "deeply ashamed and embarrassed" about his arrest on suspicion of drink-driving in Hawaii.

"It saddens me to know that I jeopardised the welfare of the kind people of Hawaii, a community that I love and call my home," he said.
Kim, 39, who plays tough guy Jin-Soo Kwon in the drama, added that he would fully co-operate with police.
He was released on bail after being stopped by police early on Thursday.
Police said the actor had been driving erratically and was found to have a blood-alcohol level that measured twice the legal limit.
"To my friends, family, colleagues and fans, thank you for your kind words of support," said Kim.
"To those I have disappointed I can only ask that you accept my heartfelt apologies. I am truly, truly sorry."
The South Korean-born actor will appear in court on 23 November.
Kim - an original cast member - is the fourth Lost actor to be arrested for a traffic offence in Hawaii, where the popular TV series is filmed.
In 2005, former co-stars Michelle Rodriguez and Cynthia Watros pleaded guilty to driving while over the legal limit.
Rodriguez, who played Ana Lucia, was sentenced to five days in jail and $357 (£174) in fines.
Watros, seen on the show as the character Libby, had her driving licence suspended for 90 days and paid a $312 (£152) fine.
And last year, Adewale Akinnuoye-Agbaje, known as Mr Eko in Lost, was arrested for a traffic offence, and was accused of disobeying a police officer and driving without a licence.
The charges against him were later dropped, however.
