CITY police officials say they have ceased investigation into the case of a Canadian man who was hit in the head by a brick thrown from an SUV last month, without making any arrests.

At least eight expats have been struck by brick-like projectiles within the span of a few months – each has reported being hit by a brick or stone thrown from a passing SUV or pickup truck.

Former Post reporter Patrick Falby is the only expat known to have reported the incident to police, after being hit in the jaw by a brick on July 13.

But Sok Chhorn, the police chief in Daun Penh district’s Chey Chumneah commune, said yesterday that police were no longer investigating Falby’s case.

“We have not found the suspect.... We are not in the process of investigation,” he said. “There is no case anymore.”

The United States Embassy is in the process of updating its website to warn prospective travellers about the attacks, a measure that may deter tourists from visiting Phnom Penh.

“There was no special meeting on the issue at the embassy, but the soon updated website link on country-specific information will include information on the brick throwing,” an embassy spokesman said yesterday.

Travel advisory websites are also warning travellers about the spate of brick attacks. Website Wikitravel.org has listed “unprovoked brick attacks” as one of the city’s main dangers.

On Thursday, Voice of America reported that two eyewitnesses saw the arrest of a man as he was attempting to throw a brick at a foreigner from a Toyota Vigo pickup truck outside Wat Ounalom at around 11pm on Wednesday. The witnesses said they believed the man was the son of a high-ranking government official.

But Daun Penh police chief Hun Sothy said yesterday that he “did not know” about any arrest. National Police spokesman Kirt Chantharith also denied knowledge of the arrest.
