Two women will face court on Saturday and a boy will appear on Monday over the alleged assault of two paramedics on Thursday evening in Reservoir.

The three have been remanded in custody after they were charged on Friday with a range of offences over an incident that left one paramedic with a broken foot, cuts and bruises after he was allegedly kicked, punched and repeatedly knocked to the ground by the trio.

The male paramedic was due to have surgery on Friday, but his colleague, who was struck on the back of the head as she went to his aid, did not need further medical treatment.

A police spokesman confirmed a 15-year-old boy was arrested by Darebin detectives at a house in Banksia Street, Ivanhoe, about 1pm Friday. He has been charged with the intentional serious assault of an emergency service worker and other assault and theft-related offences. He has been remanded to appear in a children's court on Monday.
