Thiruvananthapuram, Mar 7: Congress MLA Thiruvanchoor Radhakrishnan on Wednesday carried a used tear gas shell to the Kerala Assembly.

Showing it to the Speaker, he said that the tear gas shells being used to disburse Youth Congress protesters last week were beyond their expiry date, and police are still using them.

The Left Democratic Front (LDF) legislators created a huge uproar in the Assembly citing that the MLAs are not supposed to bring firearms inside the Assembly. Kerala Chief Minister Pinarayi Vijayan too intervened calling it a huge security threat.

Thiruvanchoor later handed over the tear gas shell to Assembly officials. The tear gas shells were reportedly used by the police against Congress workers last week who were protesting the murder of Shuhaib, a youth Congress worker. The 30-year-old Congress worker was hacked to death, while two others were injured in Kerala's Kannur city.
