Pratapgarh (UP): Raging fire engulfed a large bakery unit on Allahabad-Faizabad national highway around 2 pm this afternoon, causing a loss of about 25 lac to the owner Bipin Agarwal. However, the workers and labours came out safe. The fire was caused by short circuit in the outside electric poll from where power supply was given, and by the time it was noticed by the neighbors, the entire building was surrounded by smoke and fire. At least 5 fire brigade units were engaged for about three hours continuously before the fire could be controlled. The national highway was blocked for two hours, and the traffic was restored only when the fire came under control.
