WESTBORO — A Worcester man arrested Friday stabbed his girlfriend in the neck with a crack pipe because she wouldn’t hide his drugs, authorities say, and later held her against her will at a Sturbridge hotel. Carlos Gonzalez, of 68 Mason St., Apt. 3, was ordered held without bail Monday in Westboro District Court, and is likely to face additional charges in Sturbridge, a prosecutor said. Gonzalez was arrested by several police agencies at a Sturbridge hotel Friday, two days after authorities say he stabbed his girlfriend at a storage facility in Shrewsbury. Authorities responded to the Extra Storage Space at 53 Clinton St. around 5:45 p.m. for a 911 call of a woman being stabbed in the neck.
