Jiyayi Suleyman became Nashville's first Kurdish police officer in 2012.
It was a source of pride for both the community and the department.
"He was the first Kurdish cop, so he made all of us proud," said Hamid Hasan, the owner of House of Kabab in Nashville.
Now Suleyman is out of a job and in trouble. He's the subject of a criminal investigation.
According to an investigative file obtained by News4, Suleyman was a member of the Kurdish Pride Gang, a group known for selling illegal guns and drugs.
Police said he lied on his application about who he was and who he hung out with.
Once on the inside, he used the TBI's computer program to look up fellow gang members which is against the rules.
"I am very surprised, honestly to god, I am so mad too because this is not good for nothing," said Hasan when asked by News 4.
Investigators said they caught Suleyman associating with other gang members at House of Kabab.
Even after police arrested those gang members for selling drugs and guns they said Suleyman continued to associate with them.
A search warrant revealed pictures of Suleyman flashing gang signs and wearing gang colors before he ever joined the force.
Hasan is adamant no gang activity ever happened at his establishment.
"It's bad because he did so much for this community, not for the Kurdish community, the whole community," said Hasan.
Meanwhile many others in the Kurdish community, who were once so proud, tell News 4, they're now disappointed.
Suleyman resigned from the police department in March. News 4 has not been able to reach him.
Officials with Metro said they can't comment because of the pending criminal investigation.
