Bulgaria’s Interior Ministry special task team has arrested notorious crime figure Dimitar Vuchev aka Dembi over the murder of controversial radio host, Bobi Tsankov, according to reports.

Tsankov is known to have been very well connected with underworld figures, including Vuchev.

The name of the crime boss has been linked with several contract murders, beatings and illegal drug trafficking.

A September 2004 shooting at a car with Dembi and two bodyguards inside closed the "Lyulin" tunnel in Sofia for hours. Dembi survived the attack.

In December 2006 there was another attempt on his life. Shots were again fired at his car parked in front of a bar in Sofia's "Simeonovo" suburb.

In February 2009, Dembi implicated another alleged Bulgarian mafia boss, Zlatomir Ivanov aka "Baretata" ("The Barret"), in being the mastermind behind several of Sofia's emblematic and high profile gang killings.
