The joint programme was held in collaboration with the National Institute of Haematology and Blood Transfusion and other hospitals.
"This is really a noble and humane act. Some officers have donated blood 40 times and thousands of them have donated 10 to 30 times," said Major General Dao Thanh Hai, deputy head of Hanoi Department of Public Security.
The blood reserve for hospitals is running out, especially for blood types O and A. Due to the complicated situation of the Covid-19 pandemic, many people have been reluctant to go out to donate blood while demand never ceases.
Hai said since the police are those who often witness serious accidents firsthand and know how desperate the patients need blood donation, they must show responsibility and compassion. Give blood, save a life, he said.
