Security has been stepped up in India's bomb-hit capital Delhi a day before the Hindu Diwali festival gets under way.
Extra armed police are patrolling the streets and residents have been urged to stay vigilant during Diwali, and the Muslim Eid festival a few days later.
Officials say police are following several leads in the hunt for those behind Saturday's triple bomb attacks, which killed at least 62 people.
Meanwhile, families are still trying to trace dead or missing relatives.
The death toll rose to 62 on Monday after another wounded person succumbed to their injuries, said India's home ministry.
Eighty-nine of more than 200 people injured in the attacks remain in hospital.
Police say it is likely that one group was behind all three attacks which occurred in near succession.
A previously little-known group called Inqilabi has said it carried out the attacks. Police say they are trying to verify the claim.
Reports say police have been examining mobile phone records for any calls made at the time of the attacks.
A number of people have been questioned but no arrests have been made as yet.
Extra armed police in uniform and plain-clothes are on patrol and manning new barricades as the city slowly tries to get back on its feet.
The markets where the attacks occurred were almost empty on Monday.

Figures from Sunday
"Normally on this day, the day before Diwali, you won't get any place in my shop to stand," said clothes store owner, Harsh Goplan, in Sarojini Nagar.
"The fact that I am here talking to you, talking to other journalists says it all - that there are no customers," he was quoted by the Associated Press news agency as saying.
Turnout at some temples and mosques is also said to be lower than normal.
But there are signs of a city returning to normal.
At India Gate, teenagers played cricket on lawns, tourists walked around taking photographs and ice-cream sellers were doing brisk business, Reuters news agency reported.
"It is a sad event but life has to go on," said Indian tourist Meenakshi Dutta.
The three blasts came within minutes of each other at dusk on Saturday, when many people were out shopping ahead of Diwali and Eid.

Correspondents say the explosions were intended to cause maximum damage in places frequented by people from all religions.
Reports say DNA tests are being planned on a number of unidentified bodies - many burnt beyond recognition.
Anxious relatives of several people still missing have been visiting hospitals to try to locate their loves ones.
In one morgue, three devastated families fought over the charred bodies of two unidentified children before agreeing to a joint cremation pending the outcome of DNA tests, Reuters reported.
Police have raided guest houses and hotels in Delhi for clues. Home Minister Shivraj Patil said "lots of information" had been gathered, but refused to give details.
Investigators are checking out the Kashmiri Inqilabi militant group, which purportedly claimed responsibility for the attacks on Sunday.
"This is a very old organisation, it was formed in 1996 and has not been very active recently," said Karnal Singh, Joint Commissioner of Police.
He said they are linked to Lashkar-e-Toiba, one of the leading groups fighting Indian rule in Kashmir, whose involvement in the blasts has not been ruled out.
India is home to a huge variety of militant groups, some with very localised campaigns of violence.
But Islamists have been able to mount a number of spectacular headline-grabbing attacks in the past.
