Inspector Sanjay Bharadwaj, the SHO of Prashant Vihar police stations, came to know about the woman's predicament during his routine visit to the homes of senior citizens residing in Rohini Sector 13 in north-west Delhi.
The woman informed him that she has been diagnosed with myelodysplastic syndrome, a disorder which results in ineffective production of all blood cells and requires blood transfusions.
"Knowing this I contacted my personal friends Rajeev Bharadwaj, SHO of KNK Marg, Parmod Gupta, SHO of Kotwali, and others and went to the hospital. We all donated replacement blood for her and gave the blood donation cards to her at her home," Inspector Bhardwaj said in a statement.
