According to The Star, a CCTV recording of the four brandishing machetes and a hammer, and hurriedly fleeing the scene went viral after a Kota Damansara community group posted it on Facebook.
In the video footage, the four, believed to be loan sharks, are seen at the guardhouse, frantically slashing at a piece of rope tied to the entry boom gate.
They were also seen making threatening motions at several drivers at the scene, who were forced to reverse their cars so the four could escape.
Petaling Jaya OCPD Asst Comm Mohd Zani Che Din said the incident occurred at about 2.50pm on Wednesday and that the men were seen taking off in a silver Toyota Estima.
ACP Mohd Zani said that preliminary investigations revealed the woman had not borrowed any money from loan sharks although the prevailing suspicion was that her ex-husband did, using her home address. The two divorced in 1987.
He said that police would open investigations on the case, using the CCTV footage and statements from witnesses.
