Federal police in Manaus said a TAM Airlines flight took off from Brasilia today and was en route to the city of Boa Vista.
A note left in a bathroom in Brasilia's airport claimed that a bomb was aboard the TAM jet. It had already taken off when the note was discovered, so officials routed the plane to Manaus, where it safely landed.
Authorities said a search of the plane has yet to turn up any device. But the jet remains on the tarmac in Manaus while an investigation continues.
