LOS ANGELES (AP) _ A man found guilty of marijuana possession had his conviction overturned Tuesday because a former policeman said he falsified the arrest report.

Porfirio Acosta, 41, was the 82nd person to have a Superior Court conviction reversed because of allegations of corruption among Rampart station anti-gang officers.

Acosta pleaded guilty in 1997 to possessing marijuana for sale. He was sentenced to 120 days in jail and three years probation, but the sentence was postponed until January 1998.

In addition to overturning the conviction, Superior Court Commissioner Michael Price recalled the arrest warrant.

``He's free,'' said Marie Giralomo, the deputy public defender who represented Acosta at trial. ``This is good news.''

Rafael Perez, the former officer whose revelations unleashed the Police Department scandal, gave a sworn statement in April that he fabricated portions of the arrest report.

Although marijuana was found in Acosta's home and car, Perez said he lied about having obtained consent to conduct those searches, according to court documents.
