Many ignore the posters put up by banks warning them to not hand over their money to strangers to count and pay the price.
But Kopri resident Chandrakant Parab (78) was fortunate because he got his stolen money back, thanks to two alert beat marshals.
On Tuesday, Parab withdrew Rs 1 lakh from his account at the Bank of Maharashtra's branch on Gokhale Road.
"Mashallah Sayyed (33) first made small talk with Parab and then offered to help him count the withdrawn cash," said Police Sub-Inspector J.T. Pawar, of the Naupada police station. "He diverted Parab's attention by pointing out to some problem with a note. While Parab checked the note, Sayyed slipped a few notes in his pocket. He managed to steal Rs 35,000."
After counting the money, Sayyed told Parab that the cashier had not given him the entire amount. While Parab confronted the bank officials, Sayyed slipped out of the bank and started running.
Police naik Vasant Varkhade and constable Santosh Thaga, who were on patrol duty, saw him running and got suspicious.
"We were on our way towards Gokhale Road on the bike when we saw this man running from the bank. He seemed suspicious so we decided to follow him. We parked our bike and chased," said Thagad. "We saw him head towards a housing society. So we got on the bike and caught him."
When they asked him why he was running, Sayyed told the beat marshals that his friend had gone ahead on a bike and he was running after him.
"But we were not convinced. We searched him and found Rs 35,000. We took him to the police station," added Thaga.
During questioning, Sayyed reportedly confessed that he had stolen the money from a senior citizen in the bank.
The policemen went to the bank to find Parab still arguing with the officials. Only after the police showed him Sayyed's photograph that Parab realised that he had been cheated.
Sayyed, who was arrested on charges of cheating and theft, was produced in Thane court on Wednesday and remanded in judicial custody.
