A woman in Trinidad is in serious condition at hospital after she was run over by a bus while exiting a Public Transport Service Corporation (PTSC) vehicle.

CCTV footage circulating on social media shows the moment the female passenger stumbled as she stepped off a PTSC bus along the San Fernando/Guayaguayare route, in the vicinity of Palmyra, in South Trinidad. 

As the bus began to pull away, the woman became pinned near one of the wheels. 

In the video, her left arm appears to be crushed beneath the wheel before the driver brought the vehicle to a stop. Other passengers and the driver were seen rushing to assist and pulling her clear.

In a statement issued on January 15, the PTSC confirmed it was aware of the incident and described it as unfortunate. The corporation said an internal review had been initiated in keeping with established standard operating procedures and acknowledged that footage of the incident is currently in circulation.

The PTSC also confirmed that the matter is being investigated by the Trinidad and Tobago Police Service, with whom it is cooperating fully.

The injured woman was transported to the San Fernando General Hospital, where she remains under medical care. 

The corporation said its primary concern is the health and wellbeing of those involved and that no further details would be provided at this time due to the ongoing investigations.

The incident is the latest in a series of serious events involving the PTSC in recent months. 

In September last year, 19-year-old Lysanne Julien was killed when her car collided with a PTSC bus at the corner of Henry and Park Streets intersection in the capital city Port of Spain. 

In August, PTSC bus driver Munsaf Khan, also known as Mustapha, and security officer Roxanne Phillip were killed in a collision on the Sir Solomon Hochoy Highway.
