SAN DIEGO (AP) - San Diego has filed a civil complaint asking a state court to block mortgage lender Countrywide Financial Corp. from foreclosing on subprime borrowers. San Diego City Attorney Michael Aguirre said that he would "like to see San Diego become a foreclosure sanctuary."

Wednesday's filing in San Diego County Superior Court claims Countrywide engaged in predatory lending by selling borrowers loans they could not repay and failing to adequately explain the risks of adjustable-rate loans.

The complaint names Countrywide and its new owner, North Carolina-based Bank of America Corp., along with four former executives and unnamed loan officers and securitization agents.

Bank of America spokeswoman Shirley Norton said she had not seen the complaint and could not comment.

The bank is facing similar suits from the states of California and Illinois.
