Randy Quaid and his wife Evi remain in a Canadian jail despite being granted a release from custody last week, a Canadian border official said.
The couple were arrested last Thursday in a shopping area of a posh Vancouver neighbourhood and were jailed on outstanding US warrants related to vandalism charges.
The Quaids are wanted in Santa Barbara, where they missed a court hearing on Monday on felony vandalism charges.
The pair were ordered to be released from custody the next day during a detention review hearing on 9,750-dollar bail and a promise to appear for their next hearing Thursday.
However, Canada Border Services Agency spokeswoman Shakila Manzoor said the Quaids remain in detention but would not disclose further details. The Quaids' lawyer, Brian Tsuji, declined to comment on why they remain in custody, abruptly ending the phone interview.
During their hearing last week, the couple told Canada's immigration board they are being persecuted in the US. Randy Quaid said he and his wife plan to apply for refugee status in Canada because the couple are seeking asylum from "the murderers of Hollywood".
Evi Quaid also begged a Canadian immigration adjudicator not to force them to return, alleging their friends, such as actors David Carradine and Heath Ledger, have been "murdered" under mysterious circumstances and she worried something would happen to her husband next. Heath died in January 2008 from an accidental overdose. David was found dead, hanging from a rope, in a suite at a luxury Bangkok hotel. Neither actor's death was ruled suspicious.
During a break in the proceedings, Tsuji approached the media to read a single-sentence statement from the Quaids.
"We are requesting asylum from Hollywood star whackers," he read.
