A police investigation into suspicious activity at a north Dayton home led to one arrest and the seizure of heroin Thursday night.

Two children, ages 7 and 16 , were home when the Dayton Police Department Drug Task Force executed a search warrant at 216 E. Fairview Ave.

Their father, Alonzo Robinson, 39, was arrested on suspicion of drug related charges, according to Sgt. John Sullivan, who supervises the unit.

Officers found “a number of capsules of heroin” prepared for sale, Sullivan said.

The raid comes after the task force received a tip and conducted an investigation during which Sullivan said people were coming and going from the home at all hours.

“It’s bringing a bunch of junkies into this neighborhood,” he told News Center 7.

Sullivan encouraged residents in the community to report drug-related activity by calling the police department’s tip line at (937) 333-DRUG (3784).
