Help get my brother out of prison

Good day everyone.

My brother has been in prison for months now. He worked in a spa and facials outfit, but he resigned towards the end of last year 2020 because the woman who owns the place was owing them. After he left the place, he got somewhere else where he started to work. Meanwhile, we were making plans to travel to the village for my late dad's burial around early December of 2020. As soon as we returned from the village in early January, his former boss who owned the spa outfit came with police looking for him. They took my mum when they did not see him. The woman claimed that thieves broke into her shop and stole her goods worth millions and that my brother must be provided, she went ahead and arrested his former co-workers. By the time he came to the police station, he arrested him and released my mother. 
Since then my brother has been in police custody. They later told us he has been moved to a prison somewhere in Apapa. We had to rally and get a lawyer as they asked us to, not knowing the lawyer is incompetent. We spent money in getting another lawyer just then the Judiciary went on a long strike. By the time they resumed, the lawyer asked us to bring another money. We have spent everything we have on this case. Luckily, we got another lawyer who is human enough to really help us, but he said we need to get the services of professional sureties who will stand as surety for my brother to be released. Right now, we don't have money anymore. I have not even paid my school fees. We have asked friends and family and we only been able to raise N120,000 which can only get one surety.
I am pleading to kind hearted people out there who can help get my brother out of prison. The whole thing has been affecting my mum as she constantly gets sick lately. Please help us in any way you can. I am really pleading. We need about N450,000 for the sureties and the lawyer charges. My brother has been unlawfully detained. He is innocent of the crime he is being accused of. I know he can't do such a thing. He is our first born. This lawyer has promised to really help us but now we don't have money. Please help us in any way you can. God bless you.
