The Deputy was detained early today and questioned at the States police headquarters.
When asked by the JEP, the force said they were unable to reveal the alleged offence for which he has been arrested or the reasons behind why it cannot be made public.
In a statement released on Wednesday evening, Chief Minister John Le Fondré confirmed that the Deputy had been relieved of his ministerial duties.
He said: ‘The Chief Minister has decided that Deputy Maçon is not currently capable of fulfilling his ministerial duties.
‘Due to this, the Chief Minister has removed these duties from the Deputy and will be holding the portfolio of Children and Education until further notice.
‘To respect the privacy of all individuals concerned, no further details will be shared at this stage.’
Deputy Maçon, who has served in the States for 13 years, was elected unopposed to his ministerial role last month as Senator Le Fondré’s preferred choice.
He had been acting Education Minister since the resignation of Senator Tracey Vallois earlier in the year, as well as Children’s and Housing Minister before the roles were restructured.
In a short statement, a States police spokesperson said: ‘A 33-year-old man was arrested on 24 March at a private address, he remains in custody at police HQ at present.’
The force later confirmed that the individual has been released on bail pending further inquiries.
Deputy Maçon made history in November 2008 when, at the age of 21, he was elected to represent St Saviour No 1 district and became the youngest ever States Member.
The Deputy was re-elected three years later, again finished in second place, before being returned as the district poll topper in both the 2014 and 2018 elections.
Before becoming a minister this year he stood on several Scrutiny panels, was a member of the Planning Committee for 12 years and worked in various assistant minister roles, including in Education.
