FOXBOROUGH, Mass. — A man who worked at Gillette Stadium has been charged with making a false bomb threat against the home of the New England Patriots.

The Sun-Chronicle reports (http://bit.ly/2frDn9a ) that 25-year-old Ryan Ringuette, of Attleboro, pleaded not guilty Tuesday in Wrentham District Court.

Ringuette’s supervisor told police he sent her an email which she interpreted as a bomb threat. Officials say Ringuette did not have access to bomb-making materials.

Ringuette worked for TeamOps, which provides security and other services at arenas. A police report says he had been suspended from his job for making similar threats.

A lawyer representing Ringuette declined to comment on the charges.

Ringuette was accused of threatening an attack at Attleboro High School in 2012. He received a suspended six-month jail sentence.
