A 27-year-old BBC journalist known for her in-depth investigative pieces died suddenly, her family said.

Hanna Yusuf died last week, her family shared in a Monday Twitter post.

“Many will know Hanna for her incredible contributions to journalism and for her work at the BBC,” her loved ones wrote. “While we mourn her loss, we hope that Hanna’s legacy will serve as an inspiration and beacon to her fellow colleagues and to her community and her meaningful memory and the people she has touched for many years lives on.”

Yusuf wrote for the BBC News website, and also worked as a TV news producer, the network reported. Her cause of death was not immediately known.

She spoke six languages, including Somali and Arabic, and throughout her career, had spoken with serious crime victims and whistleblowers.

Fran Unsworth, the BBC’s director of news, called her a “talented young journalist who was widely admired,” adding that her death was “terrible news.”

During her time at the network, she followed the story of British “ISIS bride” Shamima Begum — and was the first to report that Begum’s family told Sajid Javid, then the country’s home secretary, that they planned to challenge his decision to revoke the teen’s UK citizenship.

Begum also dug into allegations that managers at the local Costa Coffee franchise withheld tips and refused to pay their employees for sickness, annual leave and working outside of contracted hours.

She’d also written about why some homeless people decide to stay on the streets instead of in emergency shelters amid freezing temperatures.

Hanna had also written for the Guardian, the Independent and other outlets, according to the BBC.

During her time at the Guardian, she created a widely circulated 2015 video explaining her decision to wear a hijab at the time.

“It has nothing to do with oppression,” she declared. “It’s a feminist statement.”

Sophia Smith Galer, who worked with Yusuf at the BBC, called her “invariably the kindest, smartest and most captivating person in the room.”

“We have lost a fierce friend and a force for truth and light which stretched far beyond her journalism to the many lives she touched here at the BBC and beyond,” Galer told the network. “We will make sure her legacy of compassionate storytelling rings loud and clear in the time to come and we are going to miss her so, so much.”
