Four people, including one Turkish citizen, were arrested in the raid on the agency's Egyptian headquarters the previous day, and their whereabouts were unknown.
"This is an act of harassment and intimidation against the Turkish press and we strongly condemn it," Turkey's foreign ministry said in a statement.
"We expect Egyptian authorities to immediately release (Anadolu's) employees," it added.
Anadolu said police stormed the office on Tuesday evening, turning off surveillance cameras and cutting the internet. It said they were refused access to their lawyer.
"This hostile step taken by the putschist Egyptian authorities against Anadolu Agency staff members is a sign of their helplessness," said Fahrettin Altun, spokesperson for the Turkish presidency.
