Chonburi officials inspected Pattaya Remand Prison looking for drugs, weapons and other contraband, but found none.
Deputy Gov. Thawatchai Rodngam led the much-publicized Dec. 26 raid with 223 soldiers, police, public health officers and Banglamung District officials tossing 4,000 cells.
Inmates also were randomly tested for drugs. In 349 tests, none were positive.
