Sinead also took to social media to ask her son to contact her. The singer - who changed her legal name to Shuhada Sadaqat in 2018 - wrote on the micro-blogging platform: "Shane, your life is precious. God didn't chisel that beautiful smile on your beautiful face for nothing.
"My world would collapse without you. You are my heart. Please don't stop it from beating. Please don't harm yourself. Go to the Gardai and let's get you to hospital.
"This is a message for my son, Shane. Shane, it's not funny any more all this going missing. You are scaring the crap out of me. Could you please do the right thing and present yourself at a Gardai station. If you are with Shane please call the Gardai for his safety."
However, the Gardai has now confirmed that their search for Shane has ended.
A spokesperson told the Irish Mirror newspaper: "Following the recovery of a body in the Bray area of Wicklow on Friday 7 January 2022, a missing person appeal in respect of Shane O'Connor, 17 years, has been stood down."
