DEDHAM, Mass. (AP) — A former Massachusetts chemist accused of faking test results at a state drug lab has pleaded not guilty to five counts of obstruction of justice.

Annie Dookhan’s plea to two counts in Norfolk Superior Court in Dedham is part of a series of arraignments in six different counties, including two on Wednesday. The other was in Middlesex Superior Court in Woburn, where she faced three counts.

She didn’t comment after either arraignment.

Dookhan had previously pleaded not guilty to similar charges in Suffolk Superior Court, where she was freed on $10,000 bail.

Middlesex and Norfolk prosecutors agreed to let her go on personal recognizance Wednesday.

Prosecutors allege Dookhan fabricated test results and tampered with drug evidence while testing substances in criminal cases. The scandal threatens to unravel thousands of drug convictions.
