AI summary

Centenial Surgical Suture Ltd (Scrip: 531380) has written to BSE and SEBI requesting an urgent investigation into what it alleges is manipulative trading in its shares. The company notes an abnormal 2.67% price rise to Rs.107.80 on September 8, 2025, which it says is not supported by any corporate announcement or material change in business. It points to repeated micro-quantity trades (1, 2, 3, 4, 5 shares), circular trading patterns, and possible collusion between buyers and sellers, including related-party trades. The company claims its promoters, directors and key managerial personnel have not traded in the stock. It has invoked SEBI Act, 1992 and the PFUTP Regulations, 2003, asking regulators to seize demat records and digital devices and take penal action against brokers and clients involved.

Likely market impact

For shareholders, this signals heightened regulatory scrutiny on the scrip, which could lead to volatility or suspension of trading if SEBI finds evidence of manipulation; the company itself is positioning as a cooperative victim, so near-term impact depends on the regulator's response.
