Two persons have been arrested from Mumbai in connection with different cases of online money fraud, police said today.

Vinayak Shivaji Khandare was arrested with the assistance of Mumbai police in connection with an online fraud where more than Rs 25 lakh was siphoned off from the bank account of a Tiruchirappalli-based businessman last year.

As part of the ongoing investigation, Khandare was arrested early this week and brought to Chennai today where he was lodged in the Puzhal prison, a Crime Branch-CID release said.

Four persons-- a key accused from Hyderabad and three 'money mules' from Chennai and Bangalore-- have been arrested in this case where the hackers managed to transfer the amount from the victim's bank account without his knowledge.

A mule is a person to whose account the funds are transferred. Later, after retaining a commission of 8-10 percent, the mule remits the rest of the amount to other accounts provided by the perpetrators of the crime,it said.

Mobile phones and bank documents were recovered from the arrested, the release said adding both were brought to Chennai today and lodged in prison.
