Police in Juja, Kiambu County are investigating the circumstances surrounding the sinking of a car into a dam, resulting in two deaths.

The victims, a man and a woman, were in their vehicle, Nissan X-Trail, when it gently moved and sank into the dam, eyewitnesses said.

It remains unclear what led to the car rolling into the dam without the two attempting to hop out.

Was it deliberately driven into the lake? Was the gear shift mechanism on neutral and, therefore, rolled into the lake without the occupants realising it? These are some of the questions being asked.

According to witnesses, the vehicle was parked on the shore of the dam on Tuesday night, January 17 before it slowly began moving into the water at around 10pm.
