"Panic gripped a busy market area here on Friday after a major fire broke out in a commercial building in the Lalbagh area," police said. There were no casualties.
"The fire erupted from the third floor of the building and soon spread to other floors. It is under control now and the flames will soon be doused completely," Lucknow's Chief Fire Officer Rajendra Tiwari told reporters.
The multi-storey building houses several outlets of cars and automobiles spare parts.
According to officials, several people were inside the building when the fire broke out. While some managed to get out by themselves, others were rescued by fire-fighting officials and police.
"The exact cause of the fire is yet to be ascertained. However, we believe it took place because of an electric short-circuit," Tiwari said.
A similar fire had erupted in the Novelty Aliganj Hall on Thursday evening.
