LAS VEGAS (AP) — Defense attorneys are seeking the release from jail of the Australian-born 13th Duke of Manchester, who has been in custody for nearly three weeks in Las Vegas on felony and misdemeanor criminal charges.

One of Alexander Montagu-Manchester's court-appointed lawyers, Robert O'Brien, said Thursday that his attorneys are concerned about his medical condition.

O'Brien says they'll ask a judge on Friday for his release on the grounds of "medical necessity."

Montagu-Manchester has been jailed since Aug. 12 on a felony false police report charge that a judge said violated terms of his release on a previous burglary charge.

Montagu-Manchester has denied committing any crimes.

He says he's suffering effects of a head injury received in a street attack June 8.

He also has a deep cut on his left thumb that he's accused of falsely blaming on an attack by his wife.
