Nine hunters were arrested in Harford County in five incidents Saturday, Maryland Natural Resources Police said.
Officers on the ground and aboard a helicopter equipped with infrared radar conducted the daylong operation.
In a 9 a.m. incident, police arrested Kevin Price Foor, 24, of Aberdeen.
He was charged with hunting without a license, possession of a deer killed by firearms out of season, possession of an untagged deer and hunting without permission on private property.
In an 8 p.m. incident, police said Christopher Joseph Hoeck, 23, of Darlington was spotlighting deer along Day Road in the northern part of Harford County.
Spotlighting, which carries a maximum fine of $1,500 and possible five-year suspension of a hunting license, is the shining of a light on a field or woodland to immobilize an animal, making it an easy target, police said.
Mr. Hoeck was wanted in Colorado on a federal warrant for theft and giving false information to authorities, police said. He was held without bond at the Harford County Detention Center until extradition could be arranged.
About 8:30 p.m. in the Spring Hill-Level area, three Aberdeen men were apprehended for hunting violations.
Arrested were brothers John Robert Kennedy, 21, and David Daniel Kennedy, 23, and Gregory Cone Morris, 38.
They were charged with jacklighting, a term that describes when a hunter uses a spotlight and is carrying a weapon capable of killing deer. It carries a maximum fine of $2,000 plus a possible five-year suspension of a hunting license.
At 11 p.m., NRP officers nabbed Edward Austin Rembold, 24, of Aberdeen, and William Cleveland Cody, 31, of Havre de Grace, on charges of spotlighting.
Officers also arrested Robert Edward Raines, 27, of Baltimore, and David Allen Dubois, 21, of Aberdeen about 11 p.m.
The men were charged with jacklighting and possession of a deer killed by firearms.
Both deer seized Saturday were donated to charity, police said.
