D.C. police arrested Roger W. (Roddy) Simkins Jr. and an associate on a gambling charge Sunday after searching several locations, including Simkins' house in Northwest Washington, police officials said.

Simkins, 37, son of the late well-known Washington gambling figure Roger W. (Whitetop) Simkins, was charged with setting up a gaming table after police, armed with search warrants from D.C. Superior Court, raided Simkins' house at 1702 Shepherd St. NW, as well as a nightclub on 14th Street NW and a house in Northwest Washington, D.C. police officials said. They said several sports betting cards were seized in the raids.

Ocean City police also arrested Nicholas Katsouros, 50, of 1755 94th St. in Deer Point, Md., outside Ocean City, after a search of his home Sunday. Katsouros, who police officials said is a longtime associate of the younger Simkins, was charged with taking bets on sports events and possession of marijuana.

The arrests capped a five-month investigation by members of the D.C. police department's gambling squad, police officials said. Police alleged in court documents that they traced more than 1,600 telephone calls made to and from Simkins' house between June and last week.

A District police affidavit on file in D.C. Superior Court alleged that Simkins' activities constituted a "major sports betting operation."
