SINGAPORE - Jover Chew, the owner of Mobile Air, was reportedly involved in a dispute with his wife Winnie Koh, who called the police on Sunday night.

Although Ms Koh, 32,told reporters in May that she had left him, they apparently still live together.

She returned home on Sunday night to find that Chew, 33, had changed the code on the digital lock, Shin Min Daily News reported.

Shin Min reported that she called the police as she was angry she could not get into the apartment.

Ms Koh's father, Chew's mother and other relatives went there later, but both families refused to be interviewed on the scene.

The families had a loud discussion in the apartment for about an hour before leaving at around midnight.

Chew and Koh continued to argue after their family members left, Shin Min added.

The police said they had received a call requesting assistance at 9.16pm on Sunday night in a case of dispute.

Both parties managed to settle the matter amicably and no further police assistance was required, police added.

Chew is known for allegedly overcharging a Vietnamese tourist for a mobile phone at his Sim Lim Square shop in 2014, and is facing charges of cheating and criminal intimidation.
