"There has been thousands of encroachments and illegal constructions besides grabbing of wakf and nazul land in the past years and they will be probed and a new law would also be brought in order to check it," Khan told news-persons here.
To a question on the issue of presidential candidate, the minister said the entire party would take a decision in this regard.
Expressing reservations on NCTC, Khan said that Muslims had often been at the receiving end of new laws.
The Haj minister also expressed apprehensions over illegal constructions near airforce stations in Agra and Bareilly.
"There are complaints about illegal constructions and development works in "no fly zones" around the airforce stations in Agra and Bareilly, and strict action would be taken against those responsible after an inquiry," Khan said.
