A man who claims to have helped rescue thousands of migrants will go on trial for people smuggling in May next year, Greek authorities have told Sky News.
Salam Aldeen, 34, has said he can prove his innocence and has never strayed into Turkish waters.
He said he was operating off the Greek island of Lesbos in January last year when he was arrested.
Mr Aldeen, who has Danish residency, said he was inspired to go to Greece to help with the migration crisis in September 2015 after seeing pictures of Alan Kurdi, the young boy found washed up on a beach.
He said: "I saw this boy Alan Kurdi and I decided to come and see what's happening for one week and that week changed my life completely and I've been stuck since that time.
"I came on my birthday, it was like a birthday gift to me."

Mr Aldeen, who can not leave Greece as part of his bail conditions, said he has helped rescue thousands of migrants.
He said: "It's difficult to say but from 5 September (2015) to around January 2016 I think around 10 to 15,000 people.
"I don't know. It's very difficult because it's boats night and day."
On 14 January 2016 he said he got a message two boats were sinking off Lesbos.
He said: "I was surrounded by three boats: one military ship, one boat from the military ship and the coastguard ship.
"I'm screaming: 'there are two boats sinking please go and help them' and they told me: 'shut up you are arrested, you're going to follow us' and they put this light on us and we couldn't see anything.
"One guy from the port authority came and saw us and said 'you again, now we're going to show you: Don't mess with us'.
"They said: 'you're going to get a lot of years, you made a big mistake, you're smuggling'.
"I was in shock. I was thinking: 'this is impossible'. All the work we did."
He said: "We took from the icloud our messages so we could show exactly where we were and we were only 2km from shore. It's 8-10km to Turkish waters."
Mr Aldeen said he had been involved in the rescue of 51 people just hours before he was arrested.
"My motive is to rescue people.
"I've been taking dead women and children from the sea.
"I've seen everything."
I asked him if he has ever trafficked migrants. He replied: "Never in my life."
He said: "I have a sign that says 'Team Humanity' on my boat.
"I've shown the coastguard my papers.
"It's hard but as long as I know what I did what should I say?
"I can't do anything but prove what I did with my evidence.
"How can they arrest us for rescuing and helping them rescue people."
A spokesman for the Greek Embassy in London confirmed Mr Aldeen's trial was set for 7 May next year.
He said in a statement: "Until then the judicial authorities - Ministry of Justice and Public Prosecution Office to the Court of Appeals of Northern Aegean - is not possible to make statements to the media.
"The indictment content (full charges sheet) is confidential, but has been handed to him at the address he has indicated in Greece."
