A source told the News Agency of Nigeria (NAN) that the aircraft developed a pressurization problem which affected the cooling system while flying at about 8,000 feet.
The source said there was no panic as the pilot properly briefed the passengers and landed safely.
According to the source, another aircraft was made available immediately and the passengers were flown to Abuja.
Acting General Manager, Public Relations, Nigerian Civil Aviation Authority, NCAA, Sam Adurogboye, confirmed the incident to NAN, saying the air return was a precautionary measure to prevent any untoward occurrence.
Mr. Adurogboye said the pilot acted according to Standard and Recommended Practices, SARPs, adding that such incidences should not be sensationalised.
"The pilot must have observed something which necessitated the return. That is the normal precautionary action he is expected to take.
"Once such incidence occurs, it is mandatory for the airline to make a report to the NCAA," he added.
Mr. Adurogboye also restated NCAA's commitment to the safety and security of Nigeria's aviation sector. NAN
