SOUTHBRIDGE - Police arrested a man and a woman and allegedly confiscated three unlawful guns, heroin, cocaine and a bulletproof vest during a raid on two apartments in the same building this week.

The arrests came after a long investigation by police with the assistance of the Central Massachusetts Law Enforcement Council and the South Worcester County Counter Crime and Drug Task Force, Police Chief Shane D. Woodson said in writing.

Yomayra Vazquez, 26 and Eliud Irizarry, 36, who live in different apartments at 99 Cross St. were arrested Friday. A warrant has been issued for a third suspect in the drug trafficking ring who was not home at the time. That person was not named.

Vazquez, who lives in the third-floor rear apartment, was charged with possession of a large capacity firearm without a license to carry, improper storage of a large capacity firearm, possession of a firearm without a license to carry, unlawful possession of ammunition, possession with intent to distribute heroin, possession with intent to distribute cocaine and conspiracy to violate the drug law, Woodson said.

Irizarry, who lives on the first-floor rear, was charged with possession of a firearm without a license to carry, unlawful possession of ammunition, improper storage of a firearm, possession with intent to distribute heroin and possession with intent to distribute class E Gabapentin. He was also arrested on an unrelated warrant, he said.

Police and members of a SWAT team from the enforcement council raided the apartment building at about 6:12 a.m. During the search of the two apartments they allegedly found a 9 mm large capacity firearm, a .22-caliber revolver, a .380-caliber gun, ammunition, a bulletproof vest, approximately 17 grams of packaged cocaine, 25 grams of packaged heroin, pills suspected to be Gabapentin, drug paraphernalia and cash believed to have come from drug sales, Woodson said.

A 6-year-old and two 10-year-olds were in the third-floor apartment at the time of the raid. A relative not involved with the investigation took custody of them, police said.
