The son of Mustafovi, in whose home the police have broken in, has been working as a pimp with the police's target, Dzhem Mustafa, Bulgaria's interior minister has announced.

Minister Tsvetan Tsvetanov explained Wednesday in the Parliament the details for the incident in the southern town of Kardzhali, in which plainclothes police officers beat up by mistake a family during operation.

According to the minister's explanations, on May 18 the police received tip-off alleging Dzhem Mustafa of involvement in prostitution rings. He has been convicted to 2,6 years imprisonment for procuring and was released at the end of 2009.

The police have checked and confirmed the information, using special surveillance devices. The Prosecution's Office has been informed and the action plan was scheduled for July 23-26.

Tsvetanov has explained that the surveillance on July 23 has established that Karim Mustafov, the son of the Mustafovi family, has ordered two prostitutes from Dzhem Mustafa for two friends of his.

The police have followed the girls from their taking off to their stopping at the address of the Mustafovi family, in front of the father's car.

After a while the police have established that the prostitutes have gone away and went to the family's address. After they have introduced themselves as police officers, the father, Sabahatin Mustafov, let them in.

Although the father have not resisted, the police have put handcuffs on him, “which is the common practise for securing the area”, in Tsvetanov's words.

“Going towards the children's room, the police have decided that the prostitutes are there and have entered a little bit faster. These actions have caused the door to hit the daughter's head,” Tsvetanov said.

The minister has added that Karim has initially confessed that he ordered two prostitutes from Dzhem Mustafa for two friends of his, who were visiting. Later, however, he has refused to write this down in his written explanations.

Tsvetanov has announced that he has apologized to the mother, Aysel Mustafova. He also added that she would probably not agree that her son has been involved in procuring.

The minister said that the the investigation on the case will continue and that the Prosecution's Office will determine whether Karim should be punished or not.
