The driver surnamed Yuen was held for driving without a license and for possession of dangerous drugs.

He complained of feeling dizzy despite being uninjured.

His 21-year-old female friend, Kwok, who sat in the silver cabriolet's front passenger seat, suffered neck and leg injuries.

A 61-year-old female passerby sustained slight injuries in the crash and did not require hospital treatment.

Only Yuen and Kwok were sent to Ruttonjee Hospital in Wan Chai for admission.

At around 10am yesterday, the Mercedes car was traveling along King's Road toward North Point.

However, near the Fortress Hill MTR Station on Shell Street, the car rear-ended the BMW.

The Benz then skidded past the BMW, slammed into railings on the sidewalk before screeching to a halt.

The female passerby suffered slight injuries as the Benz rammed onto the sidewalk, with other passersby reporting the accident to the police.

Constables arrived at the scene at 10.38am, running ID and license plate checks on Yuen who was found to be driving without a license.

Police sniffer dogs also found a bag of cannabis inside a backpack stashed in the Benz's trunk and drug-taking tools in the glove box. Yuen was then arrested.

Meanwhile, a brace was put around Kwok's neck before the pair were sent to Ruttonjee Hospital.

Kwok's Yorkshire terrier in the car was not injured.

The Benz had a shattered windscreen, a detached tire from its left side and had its airbag deployed on the steering wheel.

The BMW also saw severe dents on its right side near the trunk.

Police said that Yuen tested positive to an on-site oral drug test.

However, they did not reveal if his positive test had to do with the car accident.

The BMW driver, Hong, who was uninjured, recalled that the Benz was moving at a high speed at the time of the accident.

"The Mercedes Benz failed to slow down in time after colliding with my car, before ramming into railings," he said.

"The female passenger in the Mercedes Benz appeared as if she was in great pain."
