12:35: Putnam City Schools spokesman Steve Lindley said Coronado Heights Elementary School is no longer on lockdown.

12:15 p.m. U.S. Attorney Bob Troester said the lockdown at Coronado Heights is not related to the federal drug sweep. Police were searching the area around the school for a suspect in the machete attack of a man Wednesday on NW 51, school Principal Bart Daniel said. The school remains on lockdown.

10:50 a.m. Coronado Heights Elementary School is on lockdown as law officers search for a suspect on a drug warrant. Putnam City Schools spokesman Steve Lindley said no one is allowed to come into or leave the school until further notice.

Executive Assistant U.S. Attorney Bob Troester said information about the warrant sweep will be released Thursday afternoon.

10:30 a.m. Law officers are conducting sweeps throughout the Oklahoma City area Thursday to round up people wanted on federal drug-related charges, authorities said.

Oklahoma City police are assisting federal law officers in the area of NW 59 and Portland Avenue.

A helicopter is being used to search backyards. Law officers on the ground are searching sheds. A canine unit has been requested to assist in the search near Coronado Heights Elementary School, 5900 N Sapulpa Ave. Information about the warrant sweep will need to come from the U.S. attorney's office, an FBI spokesman said. The charges are unsealed.
