The FBI and LAPD are investigating the suspicious white powder package that was addressed to Bristol Palin on the set of Dancing with the Stars last week.
Law enforcement sources are taking the threat seriously and are looking into the possibility that the incident is connected to the white powder scare in 2010.
According to reports, the package containing a white powder substance was opened on the CBS lot in West Hollywood Wednesday, addressed to Bristol Palin.
An enclosed note demanded Bristol be removed from the show ... or else.
Initial tests in the field revealed the powder was not harmful, similarly to the one sent to Palin at DWTS in 2010, when she made it all the way to the finals.
If she didn't get kicked off on last week's Dancing With the Stars results show, when she came in with by far the lowest score, she could get back there in 2012.
