Indian police say they have arrested three more people accused in the gang rape of a 51-year-old Danish tourist in New Delhi.

A police statement says those taken into custody Friday include one juvenile. The other two are aged 20 and 24, and both are homeless.

Friday's arrests raised the number of accused attackers in police custody to six. Police said they were closing in on at least two others allegedly involved in Tuesday's attack near a popular shopping area.

Police said the tourist was raped at knifepoint after she approached a group of men for directions back to her hotel.

She later reached her hotel and filed a police complaint, but left for Denmark on Wednesday morning.
