A contract worker has been charged in connection with a blast that injured seven people at a suburban New York college.

A gap in an underground gas connection may have contributed to the June 5 explosion at Nyack College in South Nyack.

The blast shattered windows and caused a fire that was extinguished by an in-house sprinkler system. O&R had to cut electricity to several hundred. Gas service also was disrupted to dozens of customers.

Douglas Walker of South Nyack was charged with misdemeanor reckless endangerment and assault on Tuesday.

Police tell the Journal News (http://lohud.us/1201UTr0 ) Walker’s actions were believed to have been unintentional. But Police Chief Brent Newbury says “he should have been more responsible.”

Walker was released without bail. He couldn’t be reached for comment Tuesday night.
