Denied disabled parking

I took my special needs daughter to Pasar Seni in KL yesterday; she’s 21 and mentally-challenged. I parked in an OKU (disabled) parking lot but was asked by security guards to move – it’s only for wheelchair-users, it seems.

I have a Majlis Perbandaran Subang Jaya (MPSJ) OKU sticker on my car, and I’ve never faced this problem in Subang Jaya. Does this mean the MPSJ sticker is not valid elsewhere? MPSJ understands that the OKU symbol does not apply only to wheelchair-users. It’s important I park in that lot because my daughter does not understand busy traffic, and the farther away she is from our destination, the more risk she faces.
