DCI called me after buying gummies

So, very quickly, I ordered gummies this morning from some guy on WhatsApp. I paid him, then he sent a bolt guy.

30 mins later, the bolt guy still hadn't arrived. I called him, his phone was off. I text back the guy on WhatsApp that delivery guy's phone is off. He doesn't reply.

A few minutes later. I receive a call from some gu, says he is DCI. He speaks so much Kiswahili that I can barely hear him(I'm not Kenyan), but the gist of it was:

"We caught the delivery guy, says this stuff was for you. We want you to come to DCI cause the guy you bought from is a suspect we are looking for. His number is not even registered to him, and we can see that you sent him money." He threatened me not to bullshit him, and that I could be a witness.

I tell him I'll come in 2 hours. Now it's been 2 hours later. He just called again. Told him I'll come. But I'm starting to have doubts. I'm thinking of throwing my line.

I'm worried they will track it to my passport and put a flag on it or something.

True caller shows me his number is DCI Anti unit. So maybe it's legit,idk. True caller shows me the Delivery Guy's nbr is, "Pretending to be Delivery Guy".

I was actually gonna go until true caller showed me that pretending stuff.

If I throw my line, can they find me?

Like, man, I literally moved here 2 weeks ago to try and make a life in Kenya. And already I'm in this sh**.
