The arrest of Jacob Martin in a seven-year-old case was only possible after Delhi Police launched a massive drive to clear pending cases.
In the past four months, over 600 people involved in human trafficking have been arrested, helping Delhi Police clear more than 1,000 cases that were pending since 2002.
According to a senior police officer, there were 2,178 pending cases in November 2010.
Now, though, the number has reduced to 1,000.
"We have got extra staff and cleared cases almost till 2009. We have to deal with various agencies, state police and the court. Through collective efforts, we have managed to clear a majority of the cases," said RA Sanjeev, deputy commissioner of police, (Indira Gandhi International Airport).
"In half of the cases, we have arrested the accused, while in a few cases we have got non-bailable warrants issued from the court," Sanjeev added.
According to police, in a majority of the cases, the accused were agents who had sent passengers abroad on fake passports or visas.
"In these cases, passengers were deported but the agents managed to evade arrest. In most cases, the agents belong to Punjab. We have contacted Punjab Police to help us arrest them, Sanjeev added.
Police said most of these cases related to forgery of documents like passports, visas and forged immigration stamps.
"If we start arresting the agents wanted in pending cases, we might be able to curb human trafficking," he further said.
Even in the case of Jacob Martin, Delhi Police was first pulled up by the court for delay in arresting.
"We are aware that the number of pending cases is on the higher side. But we will be able to clear them," he added.
The case came to light after one Nimesh Kumar was found travelling on a fake passport.
During investigation, police had repeatedly asked Martin to join the probe but he did not.
