This ill 3-year-old became a Garda for the day and had the BEST time

A 3-year-old has been touring the country on a mission to realise his dream of becoming a police officer. 

Following a big day out at the Garda HQ in Dublin back in September, Ceejay McArdle has been travelling across the country helping the Gardaí out on their daily duties. 

And judging from his Facebook page, he is doing a darn good job too. 

The Monaghan native suffers from leukaemia and is to be undergoing rigorous treatment until 2018. 

But that's not stopping him from having his moment with local police officers who have been taking the sick child under their wing and welcoming him onto the force. 

From sectioning off crime scenes to making arrests, we reckon Ceejay definitely has a future in the business. 

"Castleblayney's youngest Garda recruit and cancers worst enemy!!" reads his social media page and we can't help but agree.
