Hari Kishan and his wife Rashmi were apprehended from Banda, a senior police official said. With this seven persons have been arrested in connection with the last Friday's robbery.
Some cash has been recovered from them, the official said.
The gang had waylaid the cash van, pinned down a security guard and shot him after he tried to snatch their weapons. They fled the spot in the cash van leaving behind the car in which they were following the vehicle. The guard later succumbed to bullet wound.
It was a raid at Harkishen's house in Khirki that helped police in its trail. The key of the looted cash van was recovered in his house.
Harkishen is the second person, who was allegedly involved in the actual robbery, to be arrested. One Deepak Sharma, who was with Kishan and others, was arrested earlier.
Two youths, who were allegedly involved in the planning were also arrested besides two relatives of a suspected robber who helped them in hiding a portion of the money.
Investigators have found out that four youths were spotted by some locals in Khirki with big boxes on Friday. A portrait of one of the suspects was sketched with their help.
From their description, police managed to get photographs of two criminals, which the eye-witnesses confirmed as those they saw robbing the van.
Several teams covered Hauz Rani and Khirki, and verified recently evicted tenants besides checking other details with property dealers.
Police on last Saturday managed to identify the house which was believed to have been used by the suspects. It belonged to Hari Kishan who had shifted recently and purchased it in his wife's name.
Raids were conducted at this house and from there, police managed to recover the keys of the cash van, which was abandoned by the gang. Some other documents were also seized from the spot which indicated that the suspects had visited and stayed there, the official said.
