Dutch authorities have arrested four suspects after uncovering a weapons cache in an Amsterdam office building on a tip from authorities in Northern Ireland, according to AP. The National Prosecutor's Office says that more than 150 firearms were found, including automatic Glock pistols and Steyr submachine guns with silencers. It says three men aged 41, 42, and 53, and a 27-year-old woman were arrested on suspicion of possession and sale of illegal firearms. Thursday's statement says the investigation by Irish and Dutch organized crime investigators also led to the seizure of 14 kilograms (31 pounds) of heroin and the arrest of a suspect in Northern Ireland earlier this week.
