Sacked Uttar Pradesh minister Amarmani Tripathi will appear before the Criminal Investigation Department of the state police on June 16 for his alleged involvement in the murder of Madhumita Shukla, a Hindi poetess.

Madhumita was gunned down in her two-bed room apartment in Lucknow's Paper Mill colony in April this year.

Tripathi's wife Madhumani has also been summoned for interrogation.

Unmarried Madhumita was seven-month pregnant when she was killed. A sample of her foetess was sent for DNA testing to a laboratory in Hyderabad last month.

Tripathi, who served the summons on Thursday, has agreed to appear before the CID at 8 pm on Monday.

A Congress defector, Tripathi is listed as a 'history-sheeter' in UP police's records and has as many as 33 criminal cases pending against him in different courts.

He is widely believed to have been close to Madhumita.
