"Following intelligence report, a robust patrol team was dispatched to raid suspected criminal hideouts at Ehweru community in Ughelli North Local Government Area, this morning.
"The team was able to track down and arrest hoodlums known for terrorising commuters plying the East-West road between Ughelli to Patani.
"The team arrested 5 suspects which include Messrs Oruno Egbede, Atiyoyo Rewemuesere, Peter Kehinde, Wilson Godbless and Friday Odede and recovered 1 Locally made gun, 1 dagger and a cutlass from the suspects.
