Ex friend was caught outside my workplace with a knife

I cut my friend off at the end of last year and tbh I did it because I had enough of his childish/immature behaviour and after he sucker punched me I saw no choice to let go of it

I gave him a chance to say sorry so about 2 weeks ago, I created a burner Instagram account and reached out to him. He said that he was sorry and that we were best friends and how we were brothers for life and how I shouldn't throw away our relationship (of 6 years)

when I asked him to simply say sorry for his behaviour and him sucker punching me, he said "I am who I am, I shouldn't say sorry for that" and hearing that, I just blocked him and deleted the account

so about him being caught outside my workplace, the security guard said he had a cleaver in his bag and he was asking the security guard to tell me to come out of my workplace but thankfully the security guard asked to check his bad as per standard protocol and he found the cleaver and my friend couldn't explain why he had it

anyway long story short I was questioned by police and he was arrested

I won't say much about what happened afterwards but yeah
