A West End property owner is suing Bank of America Corp., asserting its agents mistakenly seized a vacation house he owns free and clear, then changed the locks and shut the power off, resulting in the smelly spoiling of about 75 pounds of salmon and halibut from an Alaska fishing trip and other damages. Dr. Alan Schroit filed the lawsuit Monday in the 122nd State District Court in Galveston against the bank with which he has neither a relationship nor a mortgage. Schroit, a retired professor at M.D. Anderson Cancer Center in Houston, is suing for wrongful invasion of his house in the 4100 block of Green Heron Drive in the Pointe West subdivision. He filed the lawsuit after he and Bank of America were unable to agree on a settlement, attorney Barry A. Brown said.
