The two men approached a man around 1:15 p.m., displayed a gun and told him to hand over his wallet. The men fled on foot after the man gave up his wallet.
No injuries were reported, according to Deputy Rose DeJesus.
Law enforcement vehicles set up a perimeter east of Deltona after the call went out, and a K-9 unit was used to track the men.
Shortly before 3 p.m., the sheriff’s office said they could not locate the suspects, and suspended the search. The investigation continues, DeJesus said.
