Akon's Employee Robbed at Gunpoint

One of Akon's employees got a special visit last night -- from some home invasion robbers.

TMZ has learned four to five "black males" -- brandishing firearms -- rolled into a Van Nuys home occupied by a man who works for Akon last night and took a bunch of his stuff, including expensive stereo and recording equipment. Total heist value: $300,000.

We're also told keys to a Mercedes were stolen.

We're told detectives are on the scene right now.
