Authorities announced a second arrest today in connection with the thefts of election signs from North County roadsides.

Officers responding to a report of someone removing pro-Proposition 8 placards from in front of Olympic Resort on El Camino Real arrested Vernon Tisdall, 31, on Thursday afternoon, police spokeswoman Lynn Diamond said.

Earlier in the day, Kimberly Erlenwein, 28, was taken into custody for allegedly stealing signs promoting the anti-gay marriage measure from a center median on Carlsbad Village Drive.

Erlenwein and Tisdall, each of whom allegedly had stolen 11 of the displays, were cited for petty theft and released on their own recognizance.

Investigators are looking into reports of other thefts of placards promoting the state proposition, which seeks to ban same-sex marriage, in the coastal city, Diamond said.
