Prince George's County police officers have made five arrests and seized nearly $50,000 in cash as a result of a raid on a suspected PCP laboratory in Brandywine, a police spokesman said yesterday.

The raid was made at a house at 13900 Missouri Ave. as a result of an anonymous tip police received Thursday evening. On the premises, they found assorted chemicals that are believed to have been used to manufacture PCP, police said.

Police said information that was found at the lab led detectives to make arrests at two homes in the Fort Washington section of the county Friday afternoon.

Two adults and a 17-year-old were arrested at 13301 Colfax Dr., where police also seized $41,000 in cash, assorted drug paraphernalia and a handgun, they said.

At 2609 Rose Valley Rd., police arrested two adults and discovered $7,000 and assorted drug paraphernalia.

Police said they were withholding the names of those arrested, all of whom have been charged with conspiracy to manufacture PCP.

Although the value of the chemicals has not been determined, a U.S. Drug Enforcement Administration chemist who saw the lab called it the largest producing PCP during his tenure at the DEA, according to police officials.
