A warning has been issued by gardaí after dangerous equipment was stolen in Co Louth earlier this week. 

A  "handheld x-ray fluorescent metal analyser" was taken from a van in the Crowne Plaza hotel car park in Dundalk between 10pm on Wednesday and 9am yesterday. 

This equipment is primarily used in the construction industry to measure the density of metal in objects. 

Gardaí say the device "emits radiation, is dangerous and should only be used by trained personnel".
