Last week comedian Katt Williams accused V 103 co-host Wanda Smith's husband LaMorris Sellers of pulling a gun on him at a local comedy club after Katt roasted Wanda on the radio [click here if you missed that].
Katt is no longer cooperating with the investigation...
From TMZ
We're told investigators have reached out to Williams for more info, but he's not getting back to them. They even went to his house to talk ... but no luck.
On top of that ... we're told footage of the incident outside the club and neighboring grocery store doesn't show Sellers pointing a gun at Williams -- like Katt originally claimed.
