THE older brother of missing children Jayden and Joseph Brady says his brothers are "perfectly fine" and ran away from home because they "hated being vaccinated".
In an email to The Northern Star, Indigo Brady said he found a note from his brothers, aged 14 and 11.
"They left on their own accord … they hated being vaccinated because all of the kids immediately got sick," he wrote.
"Jaden cares for his brother so he brought him back to where he was born (Little Wategos) for a week so they could heal themselves.
"They left because they wanted to, there was nothing to do with abduction or any cult stuff.
Indigo said the Bradys were a "super loving family that didn't really do anything wrong".
"The reason they are chasing us and trying to split us apart is because my dad discovered the unified field that Albert Einstein looked for for 40 years, the thing that proves we are all connected," he wrote in his email.
"They don't want us to put it out because it proves we are all one."
Meanwhile police have arrested and charged a 38-year-old man for breaching his bail conditions.
At 6.30am today, police patrolling Broken Head Road, Suffolk Park, arrested a man walking along the roadway.
He was taken to Byron Bay Police Station where he was charged with breaching bail.
He was refused bail by police to appear in Tweed Heads Local Court today.
Police continue to hold serious concerns for the welfare of two missing brothers and appeal for anyone with any information that can assist with their location to contact them.
