(CNN) -

One of the masterminds of April's Nyanya Motor Park bombing that killed 71 people has been arrested, Nigerian police said.

About 130 people were hurt when a parked vehicle exploded in the bus station that was crowded with early morning commuters.

Aminu Ogwuche was extradited to Nigeria from Sudan, where he had taken refuge, police said.

Boko Haram's leader claimed responsibility for the April 14 bombing.

The Islamist militant group -- whose name means "Western education is sin" in the local Hausa language -- has bombed schools, churches and mosques; kidnapped women and children; and assassinated politicians and religious leaders.
