A$AP Relli claims he’s been receiving death threats after allegedly being shot by A$AP Rocky … and his legal team says it’s gotten so bad they had to contact law enforcement.

A$AP Relli’s attorneys, Jamal Tooson and Brian Hurwitz, tell TMZ Hip Hop … their client has been subjected to constant harassment online and being labeled “a snitch” following Rocky’s arrest in April.

Although Relli did not initially come out publicly as the person on the other side of the altercation, A$AP Bari proverbially pointed the finger at Relli — labeling him a “rat” online, causing the harassment to really pick up from there.

We’re told things have gotten so bad, Relli’s been in intensive therapy to cope with the situation, claiming the ordeal has disrupted his sleep and impaired his mental state.

Relli’s attorneys also rejected the notion Relli “snitched” on Rocky or the Mob … insisting a “snitch” is someone who initially agrees to do illegal activity with another individual, but then rats out that person to law enforcement when things go south. They say that’s simply not what happened here.

TMZ broke the story back in April … Rocky was arrested for assault with a deadly weapon shortly after returning from Barbados before the birth of his child.

As we reported, Relli sued Rocky in civil court, claiming Rocky shot him after the two got into an argument and said he suffered physical harm and emotional distress as a result.
