Paris Hilton’s brother under arrest

Hotel heiress Paris Hilton’s youngest brother Conrad is reportedly behind bars after testing positive for marijuana.

Conrad, 18, is in the juvenile hall in Downtown Los Angeles, according to law enforcement sources, reports tmz.com.

The Friday arrest is a result of a violation of his probation stemming from a previous marijuana arrest.

He will remain in custody until he gets before a judge. But considering it is the weekend, he might be stuck behind bars until Monday.
