Chief Constable Richard Brunstrom has attacked speeding drivers

The Sun newspaper claims its reporters used a radar gun to catch Kate Brunstrom, 18, driving at 69mph along a 50mph limit road.

The Crown Prosecution Service(CPS) is reviewing the material before deciding on whether to take action.

Her father has led a crackdown on speeding motorists, and recently compared a 71-year-old man to a "17-year-old yob" for complaining about being fined.

The CPS confirmed on Friday they had received documents and material from North Wales Police relating to the 18-year-old's case.

Chief Crown Prosecutor in north Wales Glynn Rankin is reviewing all material supplied and has sought further opinion from a Chief Crown Prosecutor in another area.

Officers fined

Last month, The Sun claimed its reporters had used a speed gun to record Miss Brunstrom breaking the limit whilst driving her family's Ford Focus near Llandudno Junction.

Mr Brunstrom has previously described speeding motorists as "anti-social" and "criminals".

In July he denied claims he was obsessed with catching speeding motorists at the expense of fighting crime.

Last month12 of his own officers were caught speeding - whilst using police cars, by anti-speeding campaign Arrive Alive.

The drivers were found to have no legitimate excuse and received three points on their licence and a �60 fine.
