LOWELL -- It started with an investigation of a bullet hole in a fence next to a home on A Street in Lowell and ended with the discovery of three firearms, ammunition, cocaine, marijuana and more than $19,000.
Now police are investigating whether some of the weapons they said they found are connected to two incidents of gunfire in the city Saturday, one of which left a man, 50, with a gunshot wound, according to Detective Lt. Frank Rouine.
Police were called to 23 A St., between Chelmsford and Powell streets, on Tuesday at 11:55 a.m., when a resident found a bullet hole in the fence on the side of his yard.
Police realized there was also a bullet hole in the side of the home at 21 A St., on the other side of the fence, and it appeared the gunshot had been fired from inside the home 21 A St.
A resident at 23 A St. who declined to give his name said he had not heard any gunshots recently.
"I was raking my yard and saw a hole in the fence. That's all I know," he said.
Police conducted a "protective sweep" of the home to make sure there were no gunshot victims inside, and discovered a large amount of marijuana, according to Rouine.
Protective sweeps are searches conducted for safety and police cannot collect evidence of a crime while performing them, so police immediately left the home and stood guard outside while they applied for a search warrant.
Officers Christian Hanson and Steve Beland were standing guard outside 21 A St.
Hanson and Beland pursued a male suspect who carried a duffle bag out of the home, watched as he discarded it, and then arrested him after a brief struggle, according to Rouine.
Inside the duffle bag, police said they found two 9 mm handguns, a "significant amount" of ammunition, a cellphone and more than $19,000.
Suspect, Sungba Dy, 23, of 16 Grove St., Lowell, is being held on charges of breaking and entering daytime, resisting arrest, assault and battery on a police officer, disorderly conduct, unlawful possession of ammunition, two counts of carrying a firearm without a license, and two counts of illegal possession of a firearm during the commission of a felony.
Dy was schedule to be arraigned today in Lowell District Court.
After obtaining a search warrant, police said they found a .22 caliber rifle, made to resemble a larger-caliber AR-15, more ammunition, more cash, about 9 grams of cocaine and a "significant amount" of marijuana, scales, and a drug ledger, according to Rouine.
Rouine said a resident, 29, of 21 A St. will face charges, but declined to release that individual's name since he is not yet in custody.
