Modding has become a big part of the gaming community, allowing players to take the game into their own hands. Fans will be thinking twice about handling "Grand Theft Auto 5" now as publisher Take-Two Interactive cranks down on a popular mod of the game by sending private investigators directly to the modder.

According to a report from GameRant, the creator of well-known "Grand Theft Auto" mod dubbed "FiveM" was visited by private investigators recently.

"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 UK or US 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 creator of the FiveM mod shared on popular website Reddit.

The modder added, "Oh, they also 'couldn't disclose any conversations they're having with other modification developers', didn't want to talk about general modification policy as 'it was just about my case' and admitted they 'looked through my source code'."

The "FiveM" mod was popular for giving an avenue for players to enjoy "Grand Theft Auto: Online" without using the developer's servers.

Another mod called "Grand Theft Auto: Multiplayer" got the same treatment. The modders posted an official statement on their website saying, "Take2 Interactive Inc. have contacted us and they asked us to stop 'GTA: Multiplayer', because from Take2's point of view 'GTA: MP' is a rival of their business. 'Grand Theft Auto' and all its content is produced by Rockstar Games Inc. and published and owned by Take2 Interactive Inc."

In an update by the modder, they said, "First of all we'd like to thank everyone for your amazing support. A huge amount of people do not want this project to end, but unfortunately there's no way out. Take2 was clear about that."

"There is another point you shoud think about: Without Take2 and Rockstar, we would not have this beautiful game and the opportunities to open the game for players," the team added, clarifying their respect for the game developers. "As developers we respect the rights of others, if they do not want that we modify their product, no matter if for good or not, we must respect that."
