A Weymouth man who allegedly put a Boston cop in the hospital by dragging him with his car yesterday made bail yesterday, met his lawyer and a probation officer in court today and then skipped out before his case was called, the Suffolk County District Attorney's office reports.

Dorchester District Court Judge Robert Baylor issued a bench warrant for Eric Nelson, 46, after he failed to answer when his name was called, the DA's office reports, adding Nelson made the initial $1,000 bail set after his arrest yesterday.

Police charge Nelson bought some heroin in a deal off Columbia Road around 11:40 a.m. yesterday and then, when stopped by police, sped away down Columbia - dragging a Boston officer with him. The officer was hospitalized with lung, spleen and back injuries, the DA's office says.

Police say they caught up with Nelson again at 37 Mt. Vernon St., where they arrested him on charges of assault and battery by means of a dangerous weapon (the car), assault and battery on a police officer, failure to submit to a police officer, resisting arrest and possession of heroin.
