The residents of Alcon Stylus, Pune alleged that they had warned the developer about the dangerous condition of the retaining wall of one of the buildings 5 months ago, but no action was taken. "We highlighted the condition of the wall," a resident of the housing society said. A portion of the wall collapsed on Saturday killing 15 people.
