Known as the “Malaysian spy in a cheongsam”, retired Special Branch officer “Blossom” Wong Kooi Fong passed away today at the age of 88.

The former 1960s undercover agent died at Kuala Lumpur Hospital from a stroke caused by a brain haemorrhage, said her daughter, Dr Christina Blossom Welch, to Malaysiakini.

“She was absolutely fine yesterday. We brought her to the emergency department yesterday morning, and she passed away earlier this morning.

“It was all very fast and unexpected. I was with her when she started to feel unwell, I was with her in the ambulance, and I was with her this morning,” said Christina.

She said a wake for her mother will be held on May 3 and 4 at Nirvana 2, Kuala Lumpur, followed by a funeral on May 5.

Born in Sungai Besi, Kuala Lumpur, Wong retired from the police force in 1993 after 36-and-a-half years of service, at the time leading the Sexual Violence, Child Abuse, and Domestic Violence Investigation Division at Bukit Aman under Inspector-General of Police Hanif Omar.

Her nickname, Blossom, derived from her childhood hobby of planting flowers, was used as an alias early in her career while conducting surveillance to gather intelligence on communist activities.

According to a 2024 article by entertainment portal Juice, other highlights of Wong’s career include her role in leading some of the earliest anti-vice operations to rescue underage girls trapped by local prostitution rings.
