DAYTONA BEACH, Fla. -

A 45-year-old former Daytona Beach firefighter was arrested Friday afternoon on a charge of sale of a controlled substance within 1,000 feet of a convenience store, deputies say.

Yusuf Abdullah's arrest took place outside of the Flagler County Detention Facility, where deputies said he is employed on a part-time basis as a paramedic.

Following a one-week narcotics investigation, Abdullah, of Palm Coast, was taken into custody by investigators assigned to the Flagler County Sheriff's Office Special Investigations Unit.

Upon suspecting Abdullah was engaged in illegal activity, investigators arranged to purchase 2 grams of powder cocaine from him. Deputies said the cocaine had a street value of $150.

"It is extremely disappointing to me to see an individual who has worked in public safety and dedicated himself to helping others, walk down the wrong path," said Sheriff James L. Manfre. "Hopefully he will have an opportunity to put his life back together again and start over."

Deputies said Abdullah has worked on a part-time basis at the Detention Facility since August 2005. His duties include performing routine medical examinations and dispensing medication to inmates at the facility.

Abdullah has been suspended without pay pending the outcome of an internal investigation and was later released from the Flagler County Detention Facility after posting $50,000 bond, according to the Sheriff's Office.
