A loud noise from the main road on Sunday afternoon shocked many at Puipaa as a speeding four-door hatchback allegedly driven by a policeman in uniform crashed into the back of a black Toyota Hilux.

The police officer and an old man were in the vehicle and were rushed to the hospital in an ambulance while the driver of the Hilux, Tana stayed behind to deal with police investigations.

In an interview with the Samoa Observer, Tana explained that he stopped at a three-corner at Puipaa with his signals indicating that they would turn right.

"We signaled and stopped for a while to wait for the long queue to pass so we can turn but we were shaken by a loud and strong push from the back and it was this vehicle crashing into ours from the back," he explained.

"I got out and asked him what happened and why he crashed into our car and the police officer said he was reaching down for something and when he looked back up it was too late."

Tana further explained that he was picking up his relatives, the three old men who were in the car with him arrived from Savaii, to go to a family gathering for a funeral.

Unfortunately, one of the old men could not make it to the family gathering on Sunday because of the incident.

One of the many bystanders, a teenager, Peter who was walking with his friends on the side of the road also supported the explanation from Tana saying the small car crashed into the back of the stagnant truck.

"The small white car was at fault. It was fast and the black car was just waiting to turn before they were slammed into," he said.

"The old man from the car was rushed to the hospital with the police officer because they sustained serious injuries."

Meanwhile, the police officers who drove to the scene conducted their investigations with the victims with the assistance of the Samoa Fire and Emergency Services Authority (S.F.E.S.A.) team.

Blood stains from the police officer's car were scene inside and outside of his vehicle on both front doors.

Asked for a comment, police officers who were at the scene said they were not authorised to speak to the media.
