SINGAPORE - Ground-handling firm Sats is investigating a fight that broke out on the tarmac at Changi Airport.

In a video that The Straits Times obtained, two Sats employees - both women - are seen hitting each other.

In the 26-second clip, at least five other staff members are seen trying to break up the fight.

A Sats spokesman told The Straits Times on Monday (March 18): "We are conducting a thorough investigation of the incident. We have zero tolerance for any breach of conduct at the airside. Staff in question will be dealt with in accordance with regulations."

The Straits Times understands that the incident happened on Sunday (March 17) and that the two women have been suspended.
