Simpsonville police arrested eight people Tuesday on methamphetamine charges in an investigation named “Operation Block Party,” authorities said.

Simpsonville police Capt. Kevin Threlkeld said narcotics investigators received a tip about a meth operation in the city’s Woodside Mill area in February.

He said the arrests were made after detectives served a warrant on May 31 at 210 W. Curtis Street, where officers said they found a meth lab.

Threlkeld said two people were arrested when officers served the warrant, and the other arrests were made Tuesday.

Charged with conspiring to manufacture methamphetamine, according to warrants, were Dennis R. Penland Jr., 34, of 210 W. Curtis Street; Randy L. Cox Jr., 35, of 104 Beattie Street; George F. Dean, 35, of 507 Curtis Street; Johnny W. Parker, 53, 603 South Street; Travis R. Imbragulio, 32, of 321 College Street; Allie M. Taylor, 22, Joyle J. Eddleman, 25, and Selena L.

All eight were being held Tuesday at the Greenville County Detention Center, according to jail records.
