Organisers of a silent human chain event were told to get permissions from authorities. The event was planned to highlight concerns about urban ecology. It aimed to draw attention to the loss of open spaces due to construction and development.

The event was postponed after the police asked the organisers to obtain necessary permits. This was a surprise to the organisers as similar events had been held in the past without such requirements.

Further details about the event and its organisers are available from the source publication.
