According to the group Middle East Concern, the broadcaster has been accused of incorrect registration of a TV channel, failure to hold licences for certain editing activities and failure to comply with regulations concerning live streaming of broadcasts on the internet.
Over the weekend, officers from the Ministry of Communications and Information Technology's Censorship Department came to the studios to search the property. It's claimed they proceeded to confiscate cameras and other equipment.
Studio director Farid Samir was said to have been taken to the local police station but was later released after local churches intervened.
Lawyers on behalf of Sat-7 refuted all charges and attempted to demonstrate that the Censorship Department's report was incorrect.
The Prosecutor will now determine whether the case should proceed to court. It's expected the decision could take up to two weeks.
Middle East Concern is calling on Christians in the UK to pray for the situation.
In a statement it said: "[Pray that] a. Mr Samir and his family will know the protection of the Father and the presence and peace of Jesus.
"B. Mr Samir, together with other SAT-7 leaders and legal representatives, will know the Spirit's wisdom in all their interactions with the authorities.
"C. the prosecutor will drop this case, and that there would be no further harassment of SAT-7 or other Christian broadcasters in Egypt.
"D. disruption to SAT-7's broadcasting operations will be minimal, and that SAT-7 and other Christian broadcasters will have boldness and wisdom as they proclaim the Christian message and promote peaceful co-existence in the Middle East."
