A man has barricaded himself inside a building on Gran Via in central Madrid, threatening to detonate gas cylinders. Emergency services swiftly arrived at the scene, which is a busy area frequented by tourists. The incident is unfolding on the third floor of the building, where the man is reportedly covered in blood and refusing to leave.

Local reports indicate that the man is armed with butane gas cylinders and has made threats to blow up the building. Police have cordoned off the area, and the Gran Via metro station has been closed as a precaution. A negotiator has been deployed to engage with the man in an attempt to resolve the situation peacefully.

Witnesses have described a heavy police presence, with multiple vehicles and ambulances stationed outside the building. One individual shared on social media, "I don't know what is going on, but Gran Via metro stop appears to be closed and police have cordoned off the area."

The situation remains tense as authorities work to ensure the safety of the public and resolve the standoff.
