SAN FRANCISCO (CBS / AP) -- A former San Francisco computer engineer convicted of locking other city officials out of the city's network.has been ordered to pay nearly $1.5 million in restitution.

A judge also ordered 45-year-old Terry Childs on Tuesday to forfeit the $11,000 he had on him when he was arrested as a down payment toward the money he owes his former employer, San Francisco's Department of Technology.

A jury convicted Childs last year of changing the passwords to the city government's computer network in July 2008. Following a 12-day stalemate, he surrendered the new passwords to then-Mayor Gavin Newsom during a jailhouse visit. Childs was sentenced to four years in prison last summer.

District Attorney George Gascon said the city incurred considerable expense overriding Childs' handiwork and keeping its computers running.
