At Singh's residence, Patna Senior Superintendent of Police Manu Maharaj was present. Mediapersons were allowed near the residence after a thorough check.
From Gaurichak, Modi was slated to families of victims in Kaimur, Gopalganj, Supual, Begusarai and Nalanda.
Nalanda, the home district of Chief Minister Nitish Kumar, will be the final destination of Modi. From there he will fly in helicopter straight to Patna airport to return to Ahmedabad in his chartered plane, BJP sources said.
Six persons were killed in multiple explosions on October 27 during "Hunkar rally" which was addressed by Modi, his first major political show in rival Nitish Kumar's home turf after parting of ways of JD(U) and BJP on June 16 last.
The investigation in the blasts case has pointed to involvement of Indian Mujahideen militant outfit.
Within a week, Narendra Modi has returned to Bihar to pay condolence to the six persons killed in the blasts on Sunday.
