Charles Sensesak, 20, of 505 Jackson St., was taken to Mercer County Jail after failing to post $60,000 bond after a preliminary hearing before District Justice William L. Fagley, Greenville.

On Nov. 29, the agent bought 26.4 grams of cocaine from Sensesak at his home for $1,140 and the agent arranged to buy two ounces of cocaine from Sensesak, it said. On Dec. 6, Sensesak presented two one-ounce bags of cocaine, but kept one of them; the agent paid $1,380 for the other ounce bag, according to the affidavit.

Sensesak told the agent that a supplier would provide more cocaine and the agent put the Jackson Street house under surveillance, it said.

On Dec. 12, the agent purchased an ounce of cocaine at Sensesak’s apartment for $1,350, according to the affidavit.

Sensesak was arrested on charges of possession with intent to deliver controlled substances, intent to possess controlled substances, criminal use of communications, conspiracy, and theft by failure to make required disposition of funds.
