GROTON, Conn. — A former Navy man is being detained under a suicide watch after being charged with torturing his wife in their home for nearly five hours.

The Day of New London reports (http://bit.ly/K4RZA0 ) that 36-year-old James Tapp of Groton was charged Monday with kidnapping, cruelty to persons, assault and other crimes.

The woman told police the ordeal began at about 11:30 p.m. Sunday and ended at about 5 a.m. Monday. She alleges Tapp beat her, squeezed her finger with pliers, threatened to shoot her and threatened to slice her from ear to ear with a knife.

The woman also alleges Tapp suffers from a stress disorder and brain injury from deployments to Iraq.

Groton Town police and the Naval Criminal Investigative Service are investigating.

Tapp’s lawyer declined to comment Thursday.
