On November 9, 2025, CCTV News released video footage from the scene of the Nanjing "2·23" (2024) fire incident.
On February 23, 2024, an electric bicycle caught fire in the ground-floor open space of Building 6 at Mingshang Xiyuan Community in Nanjing, Jiangsu Province, in the early hours of the morning. The fire rapidly spread to the upper floors through the building's lightwell chimney effect, resulting in 15 deaths and 44 injuries.
On November 27, 2024, the investigation report on the fire incident was released. Investigations revealed multiple violations: the electric bicycle owner had illegally modified the vehicle and used an oversized lithium-ion battery purchased online. Residents had illegally constructed platforms and stored combustible materials in the lightwell. The building's automatic smoke alarm system failed to activate, and property management was found to be disorganized with an inadequate initial response.
Previous Reports:
The official investigation report into the Nanjing "2·23" fire, which claimed 15 lives and injured 44, identified 10 individuals subjected to criminal coercive measures. At approximately 4:35 a.m. on February 23, 2024, a major fire broke out at Building 6, No. 9 Xishi Road, Yuhuatai District, Nanjing, causing 15 fatalities, 2 serious injuries, and 42 minor injuries. The direct economic loss exceeded 33 million yuan. Authorities concluded that the fire was caused by thermal runaway of an oversized lithium-ion battery in a modified electric bicycle, constituting a major fire safety liability incident.
Following the incident, Jiangsu Province established a special investigation team for the "2·23" fire at Mingshang Xiyuan, and the provincial discipline inspection commission set up a team to investigate accountability. Through on-site inspections, interviews, video analysis, expert evaluations, laboratory testing, and document reviews, the team clarified the sequence of events, causes, casualties, and responsibilities of involved individuals and enterprises. The investigation also identified regulatory shortcomings at local government and departmental levels, summarized lessons learned, and proposed corrective and preventive measures.
Cause of the Fire:
The investigation determined that the fire originated from thermal runaway of a lithium-ion battery in an electric bicycle parked in the open space on the east side of Unit 2, Building 6. The fire ignited surrounding bicycles and combustible materials illegally stored in the lightwell. Flames and high-temperature toxic smoke quickly spread to indoor areas through resident windows due to the chimney effect, with multiple factors compounding to accelerate the fire's spread and cause casualties.
Key Findings:
The investigation identified several major problems:
1.The manufacturers and sellers of the electric bicycle violated national standards.
2.The bicycle owner illegally modified the vehicle and purchased an oversized lithium-ion battery from unlicensed sellers.
3.Some residents illegally built structures and stored flammable materials in the lightwell.
4.The property management company failed to properly maintain fire safety equipment and did not detect or respond to the fire in time.
5.Fire control room staff did not follow emergency procedures.
6.Local government and departments lacked awareness of compounded safety risks related to electric bicycles, and public fire safety education and hazard mitigation in high-rise residential areas were inadequate.
Accountability:
Ten individuals—including the bicycle owner, illegal battery sellers, and the head of the property management project—have been subjected to criminal measures by the public security authorities. Seven companies involved in electric bicycle production, sales, and property services have been dealt with according to government regulations. Local officials and public servants found to have neglected duties have been rigorously held accountable.
