A power-plant equipment contractor that worked for the Venezuelan government seeks $300 million in damages from a Venezuelan bank, its chairman and another director for allegedly spreading knowingly false and defamatory information about it on the Internet.

In a lawsuit filed in Miami-Dade Circuit Court, Derwick Associates Corp. and co-founders Leopoldo Betancourt Lopez and Pedro Trebbau Lopez allege they have suffered severe damage from the actions of Venezolano de Crédito SA Banco Universal, a Caracas-based bank with business ties to Miami; its president and chairman, Oscar Garcia Mendoza; and board member Rafael Alfonzo Hernandez.
