House arrest - Part 1 Tarkov: Quest help

Come here, my dear employee. Is everything okay in the city? Some of my teams are missing. At first, I thought, “Why the hell would someone want to shut me down?” Unless they're messing with me or something. At first, I assumed it was that punk from the lighthouse, but then I got a message from Seva Shket. He told me they were being held in some kind of private prison. Have you heard about it? It's hidden somewhere in the old apartment buildings. I'd kill them if it was such a big deal, honestly. But it seems like someone would rather keep them in prison than kill the assholes who are messing with them. Here's the deal: Shket is the only one in the group who escaped, but now he's on the run, and he hasn't contacted us since he sent that message. He didn't even tell us where to find the guys, that rat-faced bastard. It's the guys' fault they got caught like bitches, and I would have told them to go fuck themselves for screwing up so badly. But the fact that someone is trying to fuck me over is unacceptable. Okay, enough bullshit. Find out where my guys are.
