Sued Over Leaky Basement
He's crushed the Celtics ... the Bulls ... and now NBA legend Pat Riley is accused of destroying his neighbor's basement ... this according to a new lawsuit obtained by TMZ.
According to the docs, Riley and his wife Christine own a beachfront property in Malibu ... which he overhauled in 2009 with new landscaping, remodeling, terracing and a new irrigation system.
Everything seemed hunky dory ... until Pat's next-door neighbors began to experience some major leakage at their property a short time after the Rileys completed their work.
In the docs, the neighbors allege their special "French drainage" system was collateral damage in the Riley renovation project ... and as a result, their basement flooded. .
Now, the neighbors want the Rileys to pay up for all of the trouble they caused ... and they want no less than $551,000.
