It relates to the application for a commercial infill on fields in Trinity which was at the centre of a censure motion against Senator Frank Walker.

He was cleared of accusations of putting undue pressure on the planning authorities during the week.

The police received papers from the Attorney General's Office on Friday.

Committee inquiry

Senator Walker had been accused by Senator Ted Vibert of putting pressure on the planning authorities.

The censure motion was defeated on Wednesday by 16 votes in favour to 23 against. Eight members abstained.

Files were passed from the planning authorities to the Solicitor General with a request for the States police to investigate if the planning law has been breached.

A police spokesman confirmed the force has decided to carry out an investigation into the application and whether it has broken the planning law.

Police now have to decide which officers will carry out the enquiries. It could be the CID.

The politician responsible for planning matters, Senator Philip Ozouf, said it would not have any effect on his committee's independent inquiry into the matter.

He is due to make a statement on that in the House in Tuesday.

Senator Walker said he was considering his position both as President of Policy and Resources and as a States member after only narrowly winning the censure motion against him.
