On Wednesday night, XXXTentacion was performing at The Observatory North Park in San Diego. During his set, someone came up from the audience and attacked him, as you can see in the video above. A brawl broke out immediately afterwards, and the rapper had to be carried offstage. You can see the whole thing below.

Not long after the incident, XXXTentacion was tweeting, responding to a now-deleted tweet by saying, "LOL YOU SHOULD SEE THE OTHER GUY."

XXXTentacion later blamed the incident on the security at the show and the venue.

Additionally, he addressed a stabbing that reportedly took place during the fight that broke out after the attack. Fox 5 in San Diego is reporting that one person was stabbed. That person has not been identified, but in another now-deleted tweet, XXXTentacion wrote, "several stab wounds, he in critical condition he might be dead in a few hours…'JUST SAYIN'."

Many people both inside the venue and who viewed video footage seemed to think that the person who attacked XXXTentacion was San Diego rapper Rob Stone. The crowd began chanting "Fuck Rob Stone," and many Twitter users were sure he was the culprit.

Stone and XXXTentacion have had tension for a while—tension that exploded when Stone got into a fight with XXXTentacion's pal Ski Mask the Slump God during a show in Los Angeles in April. In the aftermath, XXXTentacion said he would "slap the fuck out of" Stone for "putting [his] peasant hands on my brother."

XXXTentacion has also had beef with Drake in the past, and it seems Drake may have weighed in on XXXTentacion's most recent situation, too. He was apparently caught liking several Instagram comments about Wednesday's attack:

During an earlier show on XXXTentacion's current The Revenge Tour, opener Wifisfuneral was attacked, though that incident was unrelated.
