A man and a woman are on the hook for $802 for damage to a mattress and will face charges after State College police said they had sex in an unoccupied downtown apartment and left the mattress soaked in urine and semen. The damage happened between Tuesday and Wednesday.

The names of the two people aren’t being released yet because they have not been charged.

Police indicated they could face misdemeanor charges of criminal mischief.

Police said the mattress was discovered as the apartment’s tenants were moving in Wednesday.

The apartment had been vacant, police said.

The pair were seen on the apartment building’s security cameras, but it’s not known how police got their identities and tracked them down.
