Manila police say the lone suspect who carried out Friday's attack on a casino at a resort complex, that left dozens dead, was a heavily indebted 42-year-old Filipino who was hooked on gambling, according to his family.
Albayalde said Carlos, a resident of Sta Cruz, Manila, was "heavily in debt" due to casino gambling.
For his part, Fernando Carlos, father of the assailant, denied that his son was mentally ill but said the younger Carlos had "financial" and "family" problems."Wala po siyang problema sa pag-iisip (He has no mental illness)", the father said, in contrast to initial reports by the police that Mr. Carlos was "mentally disturbed".
"If he was a suicidal terrorist, then he would have gone on a killing spree", metropolitan Albayalde told The Associated Press earlier Saturday.
"If he is really a terrorist, he could have shot everybody there", said Albayalde, commenting on the security footage. Philippine police say the attacker was a tall, English-speaking white man with a mustache.
The police official also said the tall, hooded suspect rode a Toyota Avanza taxicab to Resorts World Manila in Pasay City just across the airport, from the former San Lazaro hippodrome in Manila. While the "Islamic State" militia claimed responsibility for the attack and identified the man as one of their jihadists, the government quickly rejected the claims.
He said Saturday: "Yesterday we lost so many lives because of this senseless act".
Carlos set fire to some of the gaming tables as well as a dining area and some slot machines. "We will not allow people or any threat group to use this situation to advance their propaganda or personal causes wether foreign or local".
Resorts World Manila has pledged compensate victims' families 20,000 dollars each, and released video showing how the terrifying attack unfolded.
He is said to have accumulated a debt of over PHP4 million (US$81,000) due to his gambling addiction.
"The work of ISIS is more cruel and brutal, they would simply kill people for nothing".
At least 37 persons were killed at a casino here in an attack which was claimed by the Islamic State even though the police continued to deny that the incident was terror-linked.
The Police chief said he was hoping the release of the gunman's identity would end speculations that the attack was the work of Daesh.
The Philippines has faced Muslim insurgencies for decades, though much of the violence has occurred in the troubled south, where ongoing battles with Islamic militants are taking place in the southern city of Marawi.
Carlos had entered the capital's Resorts World Casino and began shooting, before setting fire to a gaming room.
Police have ruled out the possibility that this attack was terrorism related and are not looking for anyone else in connection with the incident.
