A butcher and a painter allegedly involved in a terror plot to destroy a plane are related to Islamic State fighters in Syria, it has been claimed.
Police arrested on four Sydney men on Saturday who were suspected of plotting to bomb a flight packed full of passengers.
And an ABC report on Monday evening has revealed two of the men had family ties with Islamic State fighters in Syria, including the notorious jihadist Ahmed Merhi.
Detained painter Khaled Merhi is said to be related to the terrorist who experts said had been 'quite active in reaching back to Australia'.

'We know a few infamous names – Mohamed Elomar and Khaled Sharrouf' - he's not as famous as them,' said Deakin University terrorism expert Professor Greg Barton.
'(But Merhi) has been quite active in reaching back to Australia. He's in the news regularly, meddling with family and friends back in Sydney'.
Since arriving in Syria in 2014, Merhi has penning a series of inflammatory Facebook rants demanding his followers launch suicide attacks.
