Leaving a job without notice in case of salary delay

My friend joined a company in Jabel Ali Freezone in December 2020. Now he is about to complete 5 months in the company and they have processed his visa too.

But the problem is that in that company, the salaries are pending from the last 1 year and this guy is also not getting anything from the last 5 months.

Now he attended an interview outside Freezone in Dubai and so is he able to get released from that company without any legal actions?
