An online threat directed to the wife of Australian allrounder Ashton Agar has been investigated by government security agencies.
Madeline Agar was sent a disturbing message on Instagram, warning her about her husband's safety during Australia's first tour of Pakistan in 24 years.
The Australian team arrived in Rawalpindi on Sunday, with the first Test of the series starting this Friday.
It has been suggested the message was sent from a fake account, most likely from someone outside of Pakistan, and authorities do not believe it is a credible threat.
The message warned Agar's life would be at risk in Pakistan and also made threats against the couple's children, which they do not have.
"Cricket Australia is aware of a social media post, of which the nature and content has been investigated by the PCB, CA and combined Government security agencies," a Cricket Australia statement read.
"There are extensive security plans in place for this type of social media activity, which, in this case, is not considered a risk.
"No further comment will be made at this time."
No international cricket was played in Pakistan for a decade after a Sri Lanka team bus was attacked by terrorists in Lahore in 2009.
CA has taken serious precautions for this tour, with a large security presence on guard outside the hotel where the Australians are staying.
