The 2GB presenter said he was contacted by a young man, one of the hostages, who had orders “barked” at him in the background. But he took the call off air.

“Our world has changed forever. This morning two people are dead ... I couldn’t sleep through the night,” he told listeners this morning.

Hadley said he called both the Premier Mike Baird as well as Police Commissioner Andrew Scipione who sent a police negotiation to the station.

“Now it’s been well documented in newspapers today that I was on the receiving end of quite a bit of information that I couldn’t broadcast yesterday,” he said.

“I did have conversations with a hostage, he’s even identified as a 23-year-old. I still won’t use his name until I have his permission to do so and yes I did have a number of conversations (with) him off air.”

Hadley said he thought it was a hoax at first but called the mobile back and heard the “mad sheik in the background barking orders” with his demands.

“I phoned the police commissioner’s office, I spoke to the police commissioner personally off air, I told him what I’d been told and he said you can’t possibly say that on air, I agreed.

“I took two more calls off the young men who again had the instructions barked at him.

“I said to the commissioner and the premier when they were together, and I made a call to the mobile of the premier and I said I need help. I said I’m on air trying to disseminate this information and I’m not trained to deal with this sort of lunacy.”

Hadley, who hosts the morning show, told listeners he knew the identity of gunman Man Haron Monis but didn’t want to identify him while he had hostages inside the cafe.

The radio host said police sent an officer over who then fielded the calls.

Hadley also used this morning’s show to call for a change in the bail laws to be passed so people like Monis should not be allowed to walk free.

Monis, also known as Sheikh Haron and Mohammad Hassan Manteghi, was on bail on a charge of accessory to murder, relating to the death of his ex-wife, who was allegedly stabbed and set alight in a stairwell of her Sydney apartment complex last year.

Yesterday, Hadley revealed he was among media outlets, who had been in contact with the hostages who passed on Man Haron Monis’s demands including wanting to speak with Prime Minister Prime Tony Abbott.

Hadley said he had requests to put the hostage live to air, but refused.

“We’ve had another phone call from inside the cafe. Look it’s a minefield. I’m on the phone to police; I’m asking for advice on what to do,” he said on air yesterday.

“There are requests being made that I can’t comply with.

“They’re listening to the plea to release hostages.”

The trained police negotiator then sat with Hadley as he spoke with the hostages.
