A Tigard-based Thai restaurant chain's legal troubles continue this week with a series of lawsuits in Multnomah County Circuit Court for alleged unpaid produce bills.

According to three lawsuits filed March 8, Typhoon! locations in Northwest Portland, downtown Portland, Beaverton and Gresham owe a total of more than $88,500 in unpaid bills to Portland-based T.P. Produce. The lawsuits include attached copies of four unpaid invoices for deliveries stretching back to May 2010.

Typhoon! headquarters has not yet responded to a request for comment.

The chain has run into serious legal troubles in recent years, including a civil-rights complaint by the Oregon labor commissioner, the closure and reopening of its flagship location for unpaid rent, and a federal lawsuit for alleged slavery and human trafficking.
