Courthouses have always been a kind of community crossroads, the place where you can run into almost anybody at any time. It turned out to be that way in Prince George’s County this month, bringing together by chance detectives who had just filed papers on an arrest warrant and the man they wanted to arrest.

The outcome, said Capt. Harold Simms, who heads an investigative division for the county police, was “the fastest warrant ever served.”

The police identified the man sought on the warrant as Terrance Blunt, 20, of Bladensburg.

The police said the warrant was obtained in connection with a burglary in Beltsville on July 8 in the 13000 block of Ivy Lane.

Police said the burglary victim returned home that day to discover that jewelry, electronics and several credit cards had been stolen. Police said investigators found that one of the credit cards had been used in a nearby store. The transactions apparently had been captured on video footage, and police obtained the video.

That apparently enabled officers to identify Blunt as a suspect, according to the police account.

Police said they also learned that several pieces of jewelry taken from the home on Ivy Lane had been pawned. They said they recovered earrings and gold chains.

On July 15, police said, they obtained the warrant for Blunt.

“As they were filing the paperwork with the court commissioner in Hyattsville,” police said, “they spotted Blunt in the courthouse lobby.” He was there to see a probation officer involving a less-serious case

Police said he was arrested without incident. A preliminary hearing is set for Aug. 12, police said.
