A construction company working on a building site in Central Falls found human bones on Monday morning.
The property on Sheridan Street was once known as the Sportsman's Lounge, which was seized by the federal government in 1990 as part of a drug-trafficking probe.
A detective from the Central Falls Police Department says a forensic excavation of the site continued yesterday afternoon before it was interrupted by heavy rain. There are plans to resume the work on Tuesday.
Police have said little else about the discovery.
