Holly and Vicky were in Florita's Bar in Newcastle with a film crew earlier this week when an alleged confrontation broke out between a group of girls.
Clubgoer Hannah Kelso, 18, was reportedly left with a bloody face after she was hit with a flying stiletto and taken to hospital.
Following the incident, Holly and Vicky were arrested on suspicion of assault in the early hours of Wednesday (3 July) and taken to a police station for questioning.
They have since been released on bail and no charges have been brought. MTV have confirmed that "certain cast members" have been removed from the show.
In a statement, an MTV spokesperson said: "Following an incident during filming that has led to a police enquiry into an alleged offence by a member of the cast, MTV and Lime Pictures have temporarily suspended filming of Geordie Shore series 7 pending further enquiries.
"The decision has already been taken to remove certain cast members from the production process for the time being."
Northumbria Police have confirmed that two women, aged 20 and 25, were arrested on suspicion of assault and are "helping police with enquiries". The force has urged witnesses to get in touch.
