<h1>Education activist detained under National Security Act amid allegations of inciting deadly protests; spouse calls it politically motivated</h1> An education activist was detained under the National Security Act following allegations of instigating violent protests that caused deaths and injuries; authorities allege links to a foreign intelligence operative. His spouse and co-founder of associated institutes alleges a politically motivated 'witch-hunt,' denies financial or FCRA violations, says agency queries from the CBI and Income Tax Department were answered, and contends formal detention orders and charge details have not been provided. She challenges allegations publicly, disputes claims of anti-national conduct citing awards and international engagements, and says legal counsel will seek remedies against the detention and for disclosure of evidence. Local security measures including curfew and deployments around the institutes remain in place.
