Police arrested two Boston men in separate incidents Thursday and Friday on charges including illegal gun possession and drugs.

Late Friday, 24-year-old Robert Santos of Jamaica Plain was arrested after a driving infraction led to a chase and officers found a loaded gun and cocaine, Boston police said in a statement.

Officers on a routine patrol stopped Santos in the area of Preble Street near Mohawk Street, according to the statement. As they approached the car, Santos sped off to the parking lot of Moakley Park, where he abandoned the car and took off running.

Santos was arrested in a brief struggle after being chased across a baseball field at about 11:15 p.m., police said.


During the chase, Santos dropped a loaded .380 caliber Glock 42 handgun. Police found 32 grams of “crack cocaine packaged for sale” and “additional contraband” in his car, according to the statement.

He is expected to be arraigned in South Boston Municipal Court, police said. An arraignment date was not given.

Santos faces charges of illegal possession of a loaded gun and ammunition, drug trafficking and intent to distribute, resisting arrest, and driving charges including failing to stop for an officer and driving without a license, according to police.

On Thursday morning, police seized multiple guns and several bags of suspected cocaine after arresting a 33-year-old Dorchester man.

The man, who police said they would not identify until after his arraignment, was arrested on a warrant in the 300 block of Geneva Avenue in Dorchester at about 7:30 a.m. on Thursday, Boston police wrote on their website.

The man was expected to be arraigned Monday in Dorchester Municipal Court, police said.

Officers obtained a search warrant for the man’s home after arresting him.

At the home, they found a .30 caliber Universal Firearms Corp. semi-automatic rifle, a .22 caliber Winchester bolt action rifle, a stolen Glock 19 firearm, multiple rounds of live ammunition, and several plastic bags “containing a white powder believed to be cocaine,” police wrote.


The man is expected to face several charges in connection to the weapons and drug possession, said Boston police Officer Stephen McNulty, a spokesman for the department.
