The suspects, Solomon Bena and Vitalis Enan said they did not have a specific place of residence in Abuja but sleep in construction sites where they usually work.
An eyewitness said the suspects had already used a master key to gain access to a Hyundai SUV parked by the roadside before the owner raised alarm.
He said one of the suspects opened the vehicle parked not far from a car wash on the street and entered before the other suspect who was watching from behind jumped into the car and were about driving off before the owner raised alarm.
They were driven back to the spot where the car was stolen when a crowd that had already gathered in the area. He said the mob action was fueled by the high number of vehicles stolen in the area.
The DPO of the Utako Police Division, Mr Sani Omolori Aliyu, confirmed the incident and said the suspects would be charged to court as soon as the investigations are concluded.
