An illegal arsenal of weapons has been discovered in a burned house in the village of Katunitsa near Bulgaria's second largest city of Plovdiv.

The news was reported by the Interior Ministry's press center.

Police found in the house, property of the deceased son of notorious Roma boss Kiril Rashkov AKA Tsar Kiro, an automatic handgun with silencer, two chargers, a Browning and a Smith and Wesson, and a large amount of explosives and different caliber bullets.

According to the Chief of the Plovdiv police, Todor Chonov, the authorities went to the house after receiving information the weapons were located there. They were found in an attic. Chonov says everyone from the Rashkov clan will be interrogated.

The house is occupied by Rashkov's grandchildren. It is still unknown who the actual owner of the guns is, according to the police - they say they are working on the identification.

Kiril Rashkov is behind bars on charges of making death threats to Katunitsa residents, involving Angel Petrov, 19, who was run over and killed by a van driven by one of Rashkov's associates on September 23. The incident triggered large-scale protests across the country, some of which turned to clashes between ethnic Bulgarians and Roma. Hundreds were arrested.

Tsar Kiro was also detained on September 28.
