MANILA, Philippines -- Police are asking a hotel to provide them more video footage which could help them identify the assailants of a businessman who was beaten up by unidentified men in Makati.

With the additional footage and the testimony of the victim, Simon Paz, police were hoping to finally pin down the assailants and establish their motive for beating up Paz around midnight on Tuesday at the lobby of the Dusit Hotel.

“As of now, we don't have an idea who did this. The initial video footage we got from the hotel did not show any possible suspects,” said Superintendent Manuel Santos Jr., chief of the criminal investigation division.

Paz, a resident of Bellview Subdivision, Quezon City, was allegedly beaten up by three or four unidentified assailants.

Because of the injuries he sustained, Paz temporarily lost his memory and is still confined at the Makati Medical Center's intensive care unit.

Initial and unconfirmed reports said the assailants could be bodyguards of Presidential Anti-Smuggling Group chief Antonio “Bebot” Villar.

But Villar’s chief-of-staff, Jeff Patawaran, could not say if Villar was billeted at the hotel that day. He said his boss has had the flu since last week.

Paz also was "unable to communicate fully well," investigators said.

“Puro haka haka pa lang kasi (It’s all just speculation). We have no evidence yet pointing or confirming that information. So we really can't say that,” Santos said, referring to the alleged involvement of Villar's bodyguards.

Security guards at the hotel saw the assailants kicking and punching Paz in the lobby at past midnight Tuesday and quickly rushed to stop them, investigators said.

Paz was taken to the hotel clinic before he was wheeled to the MMC for further treatment, a report by Senior Police Officer 1 Marvin Fajilan said.

Paz’s son, Brian, told investigators that upon learning that his father had been hospitalized, he went to the hotel and was told by the manager, Nap Ludovico, that guards saw Paz "lying on the floor after hearing loud shouts."

The assailants left the scene immediately and the guards did not take them into custody, police said.

So far, the police have only talked to Paz's son, who reported the incident to the police, and some hotel security personnel in charge of the surveillance tapes.

In a phone interview, Santos conceded the police were having difficulty pinpointing the assailants and their motive for the attack.

“That's why we will ask the Dusit Hotel for more footage from the hotel's side entrances and other portions,” he explained.

He added that his investigators had yet to take a statement from Paz, who was still confined in the hospital because of his injuries.

“The victim's lawyer told us that once Paz gets better, our policemen can take a statement and we can now establish the assailants' identity and why they beat up Paz,” Santos said.
