The modders behind the popular GTA Online modification FiveM, who develop and provide an alternate online playspace for the PC version of hit game "Grand Theft Auto V," announced on Reddit that publisher Take-Two recently sent private investigators to their home, ordering them to stop their activities, according to Ars Technica.

Though Rockstar Games has been pretty lenient when it comes to allowing user-made modifications of its popular game, its parent company, Take-Two, seems to have a different stance, in particular, regarding the modders of the game's online version, GTA Online.

After all, with most of the game's revenue coming from GTA Online, Take-Two seems to have a very good reason to stop anyone tinkering on the game's web-based version. For FiveM, this realization came to fruition when two private investigators hired by Take-Two came knocking at the door, reports Metro UK.

"So I just got a pair of PIs at my door claiming to be sent by Take Two. Handing me a phone with a person somewhere in the U.K. or U.S. or whatever to 'discuss how to cease my activities with regard to Grand Theft Auto', that 'they know what happened before with Activision and want to not get the lawyers involved at this time', however they 'have tested their legal standing already and are quite certain of their point' and 'aren't willing to accept any solution other than ceasing my activities," the modder wrote on Reddit.

The FiveM mod has already drawn criticism from Rockstar Games earlier this year, to the point when FiveM's Rockstar Social Club accounts were blocked. Regardless of the ban, however, FiveM still continued on the group's work. 

With the recent P.I. visit, however, it seems like Take-Two is getting a lot more serious in its crackdown on FiveM.
