Staff at Papua New Guinea's national broadcaster say an assault on three female staff members has left the victims traumatised and other workers in shock.
Police say they have some leads in the case which involved a sexual attack on the women in a Port Moresby suburb as they were travelling home in company transport on Monday night.
The bus was held up by a group of armed men.
The acting chief of staff at NBC Television, Mulai Robby, says the staff are grateful the management has responded positively to their calls for extra security.
"The message relayed to the management was the staff members wanted an escort provided and we're grateful that the management responded positively that such arrangement of security or escort for those working late is to be provided."
Mr Robby says the women are traumatised and receiving medical attention and counselling.
