Adnan Syed has been seen for the first time since he became world famous as the subject of the podcast Serial.

The 35-year-old was spotted arriving at his post-conviction proceedings at the Circuit Court for Baltimore City on Wednesday morning.

Wearing a blue prison uniform and with a heavy beard, the handcuffed prisoner was seen entering the court house ahead of the hearing.

The first time he's been seen since the podcast was released, unsurprisingly Syed looked complete different to the high school pictures taken before the murder.

Just 17 when he was arrested, he arrived in handcuffs ready for the hearing, where his legal team are hoping to convince the judge that Syed deserves a re-trial.

Serial producer Sarah Koenig was seen arriving at court ahead of the hearing and posed for some photos with supporters outside.

Rabia Chaudry, creator of the Undisclosed podcast and a life long friend of Adnan, arrived at court alongside Adnan's defence team Justin Brown.

She caused a stir as proceedings got underway after she sequestered by the state and told leave the court, a move the defence team objected to.

Shortly after leaving court she took to Twitter to vent her anger: "I told you guys. The state plays dirty. Just a reason to get me out for rightly humiliating them."

Members of Hae Min Lee's family were reportedly spotted arriving at the hearing.

Koenig told ABC News she would not be doing any interviews while she's here for the trial as she was there to do reporting herself.

Syed is fighting his conviction for the murder of ex-girlfriend Hae Min-Lee in January 1999.

The hugely popular 2014 podcast, hosted by Sarah Koenig, examined his conviction and pointed out issues in his trial and the prosecution's case.

In November 2015, a judge granted a hearing for Syed, which will focus on new mobile phone tower evidence, as well as testimony from Asia McClain, a high school student and classmate of Adnan that was not included in his original trials.

In January 2015, McClain filed an affidavit claiming Syed's defence lawyer Crisitna Gutierrez never contacted her at the time of the original trial to be an alibi witness.

The campaign FreeAdnan is hoping the re-opening of the appeal will see the incarcerated Syed have his conviction eventually over turned.

Close friend and supporter Rabia Chaudry has been keeping supporters updated on Twitter and revealed what exactly the outcomes of the appeal hearing could be for the 34-year-old.

She wrote on Twitter last week: "Outcomes: he wins appeal, gets new trial or court sends case back up to higher court to decide, or he loses.

"Or maybe conviction gets thrown out (unlikely), and of course possible that I tackle Urick."
