Authorities are warning motorists to be on the lookout for gas skimmers capable of stealing credit and debit card numbers.
Police in Tempe and Yuma found skimmer devices attached to the interior of gas pumps in Tempe and Yuma.
Police say customers should look out for signs of tampering at the pumps, checking to see if tamper prevention stickers are broken.
All credit and debit card users should check their charges online often.
A skimmer was last found in Tucson in May. If you find one, call 88-CRIME.
