NASHUA, N.H. (CBS) – A Nashua man has been charged with stabbing two teenagers who were working for him.

Police say 67-year-old Ronald Bourdon got into an argument with the teens at his home Tuesday evening.

It's not clear what the argument was about or what type of work the teens were doing for Bourdon.

One was stabbed in the arm, the other in the abdomen.

Both were taken to the hospital. One was transferred to a Boston hospital for further treatment.

Bourdon was arrested.

He refused bail and is being held at the Nashua Police Department until his arraignment Wednesday.

He's charged with assault and criminal restraint and threatening.
