The incident happened on January 21 when the three men clad in shalwar and kameez stormed the temple waving pistols and ordered everyone inside the premises to step out.
The panic and scuffle that followed resulted in desecration of one of the three beautifully-decorated idols at the temple near the Karachi Zoological Gardens, Dawn reported.
"The people are afraid of coming here for puja now after the attack," said Maharaj Hira Lal.
"We don't know who those men were. We have never seen them before," Maharaj said.

"We are very saddened by the incident. It has really terrorised the neighbourhood," he said.
The temple has three idols of deities Shitala Mata, Santoshi Mata and Bhavani Mata.
Maharaj said the temple was built as a place for worship by his grandfather soon after he moved to Pakistan from India some 60 years ago.
"He was childless but adopted a 14-year-old boy, Mohan, who he brought up as his son. The young boy was soon married to a suitable Hindu girl, Champa Bai, who lived nearby in Soldier Bazaar. And I am Mohan and Champa's son.
"Then some eight years ago, during regular puja here, devotees witnessed another miracle when Kali Mata's footprints made from red holy powder abir suddenly appeared beside the mantel," the Maharaj said.
