Five people died of heart attacks in Bangladesh and over 100 were injured in panic-related incidents when a 6.7 magnitude earthquake hit Manipur of India, some 353 kilometres away from Dhaka.
Many in Bangladesh woke up to the tremor at 5:05 that was felt for around a minute. In the cold, the panicking people rushed to the streets while some jumped off their balconies, leading to injuries.
In Dhaka's East Jurain, Saiful Hossain Rubel, 22, died of a heart attack during the quake, said Kazi Wazed Ali, officer-in-charge of Kadamtoli Police Station.
"He was panicking, woke his roommates up, and rushed downstairs. He collapsed on the ground floor," said Wazed.

Khandakar Sohan, a constable who was in the barrack beside police headquarters, fractured both his legs after he had jumped from the first floor. He was admitted to the DMCH as well.
Gas connections snapped in some areas of the capital while some other areas suffered power outages following the earthquake.
The Met office in Dhaka claimed that the earthquake was of 6.6 magnitude and was at a depth of 40 kilometres.
However, experts said the earthquake released energy of 6.7 magnitude at its epicentre but it was felt between 4 and 5 in Dhaka, based on the soil quality of certain places.
Most people thought it was the strongest earthquake they had ever felt and that was because they had not experienced such a strong earthquake from so close to the epicentre, said professor of geology department and earthquake specialist Syed Akhter Humayun.
The professor said on the soft soil of Dhaka city, the intensity was around 5 while in areas with harder soil it was 4. The people of Sylhet felt it more than the people of Dhaka since Sylhet is closer to Manipur.
According to him, Dhaka city dwellers experienced the Nepal quake of last year between 3 and 4 on the modified Mercalli Intensity Scale.
"Even people living away from the epicentre might feel a stronger jolt if they live on soft soil," he said.
Mehedi Ahmed Ansary of the civil engineering department of Bangladesh University of Engineering and Technology said had the quake intensity been 8, the damage to Dhaka would have been severe.
Historically, Manipur is earthquake-prone, he said.

Relief and Disaster Management Minister Mofazzal Hossain Chowdhury Maya at a press briefing in the capital said the people of Bangladesh has the special blessings of Allah and that was the reason for the insignificant damage the earthquake had caused.
He said, "The people of Bangladesh are pious. Allah has blessed this country. That is why the damage was insignificant compared to the magnitude of the quake.
"Researchers had said Dhaka would be demolished if it suffered a 6.5 magnitude earthquake. We had one with 6.6.
"It is my belief that Dhaka would not be damaged even if it was hit by a 7.0 magnitude earthquake," he went on to say.
