While Tiger Memon was allegedly the mastermind of the blasts conspiracy alongwith fugitive gangster Dawood Ibrahim, Yusuf was accused of allowing his flat and garage at Al-Husseini building in Mumbai for terrorist activities.

A special TADA court had sentenced him to life imprisonment.

Yakub Memon, another Memon brother who was arrested in the case, was hanged in 2015.

At least 250 persons were killed and hundreds were injured when 12 blasts ripped through Mumbai on March 12, 1993.
