Police in the border town of Somersworth, New Hampshire, are searching for three people thought to have fled into Maine after a Saturday morning shooting.

Officers say several callers reported gunshots around 1:21 a.m.

They say they found shell casings and live rounds near a home where a fight is believed to have taken place, as well as a vehicle and a separate home hit by gunfire.

No one was injured.

Police arrested one man, 48-year-old Robert Stiffle of Somersworth, N.H., and charged him with reckless conduct and criminal threatening, both involving a deadly weapon. His arraignment is on April 6.

Several guns were also found during the investigation, and officers are still looking for three others who may have traveled into York County.
