A captured alien communicated with the KGB agent via telepathy, asking for help

The following information was all recorded from an actual report made by a former member of the KGB. The KGB member was essentially tasked with investigating this captured alien, through which he essentially discovered the following.
It all started with him heading to a secret underground base where he saw how many locks there were in the entire operation to begin with.
Soon after, he realized why, as the creatures he found inside were literally “out of this world” to say the least.
Subsequently, he arrived at the room he was to study himself and the specimen he was to examine.
He got himself a protective suit which, according to the experts there, made him not in any danger, even if the creature attacked him head-on.
When he tried to approach the alien, however, a voice began to appear out of nowhere inside his head, which made it clear that the creature could not communicate by real words, but by telepathy.
Essentially, it asked him to contact his superior and release him immediately. He talked about how he was hurt and how he needed to escape as quickly as possible.
He immediately remembered the Project Blue Book alien interview and couldn’t help but feel bad about how this creature was essentially kept in check and tested on a daily basis.
