A Boston judge has increased bail for a convicted rapist and career criminal released because evidence in his drug case allegedly was mishandled at a state lab.

Marcus Pixley was back in court Friday after being re-arrested when he didn’t show up for a court appearance Wednesday. A judge doubled his bail to $2,000 and set his next court date for Oct. 15.

Pixley is awaiting trial on 2011 drug charges. His lawyer sought bail because evidence in his case was tested by state chemist Annie Dookhan, who’s charged with obstruction of justice for skirting protocols and faking drug test results.

He has a criminal record dating to 1977, including eight drug convictions and a rape conviction.

His attorney says Pixley is being used as a “poster boy” to frighten the public when the issue is potential injustice.
