Mr Brebesh was detained on 19 January after being called in for questioning by a militia in Tripoli
Libya's former ambassador to France has died less than 24 hours after being arrested by Tripoli-based militia, a US-based human rights group has said.
Human Rights Watch said marks on Omar Brebesh's body suggest he died as a result of torture under detention.
Mr Brebesh served under former Libyan leader Muammar Gaddafi, who was toppled after a nine-month civil war last year.
The country's interim government is under mounting pressure to prevent the abuse of thousands in custody.
Mr Brebesh was detained on 19 January after being called in for questioning by al-Shuhada Ashura militia in Tripoli, Human Rights Watch quote his son, Ziad, as saying.
A day later, his family heard his body had turned up at a hospital in Zintan, about 100km (60 miles) southwest of the capital, the rights group said.
"Photos of Brebesh's body, seen by Human Rights Watch, show welts, cuts and the apparent removal of toenails, indicating that he was tortured prior to death," the group said in a statement.
