RIYADH, Saudi Arabia (CNN) -- The most senior member of al Qaeda so far has turned himself in to Saudi authorities, Saudi sources say.

Othman Al-Omari, number 19 on Saudi Arabia's most wanted list of 26, has accepted the government's offer of amnesty, according to Saudi sources Monday.

Al-Omari, who turned himself in on Sunday night, was a business partner of Shaban Al Shihri -- the first al Qaeda member to accept the amnesty when he turned himself in Friday.

Al-Omari and Al Shihri shared a vegetable stall in a market in Medina. Al Shihri, according to sources, was in part responsible for persuading Al Omari to turn himself in.

Sources said the most wanted list of 26 is not arranged in order of importance.
