Next of kin have been informed of the deaths, but the identities of the victims have not been released.

No arrests have been made, but detectives are not looking for anyone else in connection with the case at this stage in their investigations.

Flowers have been left outside the block and a police guard has been stationed to cordon off the area.

Residents were having to sign in and out when they leave the block.
