Four people were arrested after police say a woman was held captive and assaulted multiple times in an apartment Thursday.

Police say officers were called to an apartment in the first block of Balmoral Street due to a reported disturbance and possible assault.

Officers conducted a welfare check and a woman in her 20s “secretly” asked for help. She said she was attacked by other people in the apartment.

Two men and two women, aged 29 to 37, were arrested.

The victim was taken to the hospital with head and upper body injuries and later released to stable condition.

Police said the victim and the four suspects knew each other. Investigators determined the incident occurred after the victim encountered another problem and was forced into the apartment, where she was assaulted, held captive and robbed. The victim managed to escape, but was brought back into the apartment, but not before a witness called police.

The four defendants have been charged with kidnapping, robbery and assault with a weapon and remain in custody.

The accusations against them have not been tested in court.
