Hi, just posting to see if anyone is in the area of the Ardmore Hotel in Dublin.
I've been in contact with some immigrants who seem to be playing every system they can.
One couple in particular have picked a fight with me as they don't like what I think of them.
The couple are driving around as learners, with provisional licenses, but no experienced driver, with invalid/fraudulent insurance, in a car with unpaid finance.
The pair have had very few driving lessons, the male has repeatedly failed his test and has already planned in advance to make a complaint of racism when he next fails.
They have their young daughter in the car with them when they're driving.

Both are working and claiming benefits, living with in-laws and not paying council tax.
They are not registered to vote.
The female uses 2 similar first names and 3 different surnames.
The male owns land in the Cameroon.
The list probably goes on even further but thats all I know.

I don't have their address, but do have various photo's of the area where they live and the car that they drive, but no full registration.

I have both their various names and both their dates of birth.
I cannot post the pics here for obvious reasons.
Could someone give any advice on who I should report them to.
