Senator heads home after Sri Lanka run-in November 10, 2013 - 9:43PM Australian federal MP Lee Rhiannon is safely on a plane bound for Sydney after Sri Lankan authorities detained and interrogated her for hours, her office says. She was later released and allowed to board a flight back to Australia. The Greens say the Department of Foreign Affairs and Trade (DFAT) and the Sri Lankan were both notified ahead of Senator Rhiannon's trip. A DFAT spokeswoman was unable to confirm this, saying only: "The department is aware that Senator Rhiannon was questioned at her Colombo hotel earlier today by Sri Lankan immigration authorities. Senator Rhiannon did not request consular support. Senator Rhiannon has denied claims by Sri Lankan officials that her planned press conference was in violation of her visa, telling Fairfax Media she had been advised to obtain the "special projects" class tourist visa. Senator Rhiannon is expected to touch down in Sydney at 9.15am (AEDT) on Monday.
