A man arrested Thursday for allegedly robbing an East Manchester Township supermarket has since confessed to two other armed robberies, Northeastern Regional Police said in a news release.

Chad David Ryan, 39, allegedly pulled a gun on loss-prevention officers Thursday morning when they confronted him about pushing a cart full of groceries out of Giant Food Store, 205 Glen Drive.

Police said Ryan loaded the groceries into his GMC Sierra and fled the parking lot. A witness was able to get the SUV's license-plate number, allowing officers to identify Ryan, of Creek Road in Newberry Township, Chief Bryan Rizzo said.

Newberry Township Police went to Ryan's home, where he surrendered without incident, Rizzo said.

After his arrest, Ryan allegedly asked officers if the FBI was coming. When asked why the FBI would be involved, Ryan said, "because I robbed the Sovereign Bank," according to police.

Ryan then showed police a ski mask he allegedly used during a bank robbery Sept. 6, 2011 at Sovereign's branch at 4157 N. George St. in East Manchester Township, police said.

In that incident, police said, a man wielding a semi-automatic handgun jumped over the teller counter and demanded cash. The man disappeared into a wooded area east of the bank, police said.

Ryan has since been charged with robbery and other offenses related to the incident at Sovereign Bank, police said.

During the interview process Thursday, Ryan also admitted to robbing a Sheetz store in Manchester Township using the same gun and ski mask, police said.

That alleged confession matches a report of an armed robbery at Sheetz on June 17, 2011, according to police.

According to the news release, Ryan told police he has not worked since 2009 and has resorted to armed robbery as a way to support himself.

He has been arraigned on three counts of robbery. He is in York County Prison with bail set at $50,000 for each charge, according to the news release.
