OSLO: Facebook said on Thursday it is cooperating with Norwegian authorities who are probing the disappearance of a teenage girl after police earlier stated that the website had refused them access to her account.

During a press briefing on the investigation into the missing girl, Oslo police inspector Hanne Kristin Rohde said investigators had "for the time being received a 'no' from Facebook regarding access and insight into her account."

She did not specify the reasons Facebook had given for the refusal, but said the social networking site had saved the content of the account and that police would submit a new request.

But Facebook told AFP in an emailed statement that the social networking site had been assisting police in the investigation.

"We've been cooperating with the police within a matter of minutes of them contacting us and are supplying them with further information relevant to the investigation," the statement said, without providing further details.

Sixteen-year-old Sigrid Schjetne disappeared on her way home late Saturday.
