HUDSON - Authorities are resuming a search this morning for a man who jumped into the Merrimack River Wednesday night as a police detective approached him.

The incident began about 6:40 p.m. when police were called to the Maple Avenue and Fulton Street neighborhood for a report of a man breaking into cars.

According to a police news release, residents chased the man away from Maple Avenue, but a resident later found him inside a car on Fulton Street.

The man ran and police began an extensive search for him. A police detective, checking under Veteran's Bridge, noticed a man standing on the river's edge. As the detective approached him, the man waded into the river and started swimming upstream.

The officer lost sight of him and while police immediately began searching the riverbank for him, they did not locate the man or find evidence that he had left the water.

Hudson and Nashua firefighters arrived on the scene with boats, and a river search was launched. The man still was not found, and later a New Hampshire State Police K-9 team was brought in but again with no results.

Authorities are resuming the search Thursday morning, with the help of New Hampshire Fish and Game.

Police ask anyone with information about the incident or with a missing family member who could have been in the Hudson area to call them at 886-6011.
