The Woburn man who allegedly fled the state after stabbing a student and driver on a Salem State University shuttle bus last week has refused to voluntarily return from New York, prosecutors said today.

The Essex district attorney’s office will seek a governor’s warrant to get Timothy G. Wells returned to Massachusetts, the office said in a statement.

Wells, 25, is currently being held without bail on a fugitive from justice charge in Columbia County Jail in Hudson, N.Y., the statement said.

On Sept. 25, Wells allegedly slashed a female student in the hand and then stabbed the bus driver, who was trying to protect her, in the chest. Both injuries were minor. The incident prompted a two-hour lockdown of the university.

Later that day, he was arrested in Chatham, N.Y.
