Haunting security footage has captured the final moments of a young flight attendant who was found dead in a hotel room on New Year’s Day.

The video shows Christine Dacera, 23, in a hallway in the Garden City Grand Hotel in Makati, Philippines, where she was celebrating the new year with a group of others.

She and a male companion can be seen going down the hallway together and knocking on the door of a hotel room.

Eleven men have been charged with the rape and murder of Ms Dacera, a flight attendant with Philippines carrier PAL Express, who was found dead in a bathtub at the hotel early on New Year’s Day.

Their charges are provisional as police are still waiting on a toxicology report.

The release of the video came as Ms Dacera’s mother, Sharon, pleaded with Philippines President Rodrigo Duterte to deliver justice in her daughter’s “barbaric” death.

She also made a direct appeal to Mr Duterte’s daughter and Davao City mayor, Sara Duterte.

“Ma’am Sara Duterte, you are also a mum. You have a daughter too,” she said,

according to the Philippine Daily Inquirer.

“That is why I want to come out in the open because I don’t want that somebody will be a victim by this kind of brutality.”

Sharon also delivered a stern message to those responsible for her daughter’s death.

“You treated her like a pig,” she said.

“I don’t want this to happen to another woman who will be treated like that.

“Christine does not deserve this brutality.”

Ms Dacera, from General Santos City, was rushed to hospital by three friends who found her unconscious in the bath on the morning of January 1.

They had performed CPR but she failed to respond and was declared dead on arrival at Makati hospital.

Police said “lacerations and sperm” were found on her genitalia and body was covered in scratches and bruises.

An autopsy found Ms Dacera’s death was caused by a ruptured aortic aneurysm.

Makati police chief, Colonel Harold Depositar, told the Philippine Daily Inquirer the deadly aneurysm may have been caused by very strenuous activity and a high level of alcohol toxicity.

“For sure, there was force inflicted on her body because we found contusions in her leg and knees, and there’s an abrasion in her thigh,” he said.

He added that semen had been found “in multiple places in the hotel rooms”.

But Ms Dacera’s family is pushing for a second autopsy after claiming the first one was incomplete, ABS-CBN reported.

A lawyer for Ms Dacera’s family said they believed the young woman was drugged and abused before her death.

They claimed Ms Dacera “had already experienced intoxication and complained that her drinks appeared to have been spiked” during the New Year’s celebrations.

“We also believe that maybe the aneurysm was a proximate cause but it is also very possible it was triggered by the assault prior to her death,” the family’s lawyer, Brick Reyes, said, according to The Inquirer.

Colonel Depositar told The Inquirer most of the men were “practically strangers” to the 23-year-old.

“Only three of them were Dacera’s friends,” he said.

“The others were practically strangers to her, as they were only known to her three friends.”

Philippines’ Commission on Human Rights said it would also carry out its own investigation into Ms Dacera’s death.

PAL Express has issued a statement following Ms Dacera’s death, calling her an “upstanding and professional” crew member who would be “sorely missed by her colleagues and friends”.

“PAL Express mourns the tragic death of Christine Dacera last January 1 during New Year revelry in Makati City,” the statement said.

“Our desire is for the truth to come out in the interest of justice.”
