A house on Chicago Street was raided by members of the Erie County Sheriff's Narcotics Unit with assistance from the Buffalo Police Narcotics Unit on Tuesday night.
Luis Garcia Ramos, 28, was taken into custody in the house at 181 Chicago St. at about 6 p.m., said Senior Detective Alan Rozansky, head of the sheriff's drug unit.
A quantity of crack cocaine, a number of loaded weapons, marijuana and a quantity of C4 and other explosives were found in the house, according to Rozansky.
A probe into alleged crack cocaine dealing began when detectives found that Southern Tier residents were coming into Buffalo to allegedly buy from Ramos and others, Rozansky said.
The investigation started about a month ago and is continuing, Rozansky said.
Explosives found in the house have been turned over to the Sheriff's bomb squad and the federal ATF agency will also be taking part in examining the explosives, Rozansky said.
Ramos was charged with third-degree criminal possession of a controlled substance, third-degree criminal possession of a controlled substance with intent to sell, illegal storing of explosives in the house, unlawful possession of marijuana and endangering the welfare of a child, according to authorities. Ramos was at the Erie County Holding Center on Tuesday night.
