Security kicked out a Nets fans after he allegedly attacked Knicks fans with his prosthetic limb at Tuesday night’s Nets-Knicks matchup at Madison Square Garden.

This would be kind of funny, EXCEPT he may have been doing absolutely nothing wrong.

Apparently, Jeffrey Gamblero — a fixture at Nets games since they moved across the water to Brooklyn — was dancing in the stands when security asked him to keep it cool.

Check out this eye-witness testimony (sic.) a fan at the game gave The Brooklyn Game:

“(Gamblero) was being his usual self, absolutely no cursing, no negative cheering, just dancing and loud cheering for the Nets. Never attacked a Knicks fan, never got out of hand.

After halftime a guard came up and told him to “cool down and just be a fan.” Obviously didn’t know who he was. He said what did I do wrong? Should I be quiet? They said no, just cool it down. He started loudly cheering FOR the Knicks doing “go New York go New York go,” etc. The guards came back and told him to stop. He said why? Is this a library?

Then the main guard on the floor gave the signal to kick him out. He would not leave. A guard then touched his leg and he said “ouch you’re hurting me I have a prosthetic leg.” He then took off the leg, which is when things escalated.

More and more guards surrounded him as he watched the game with his leg resting on his shoulder. They tried to get him to put his leg on, threatened to arrest him if he wouldn’t, but he wasn’t moving.

He started saying “why are you doing this I just love basketball so much,” he was clearly overwhelmed.

After about ten minutes, four guards grabbed him and carried him out as he screamed in pain.

I am a lifelong Nets fan but regardless, this was one of the cruelest and most upsetting things I have ever seen.”

Come on New York. Just because your squad is losing to your sub-par, cross-town rival doesn’t mean you can kick out a fan having a good time. Even if it’s not true, try to pretend to have some class.

In the end, giving Gamblero the boot didn’t even matter; Brooklyn beat the Knicks by a score of 98-93.
