1) call police to file this case, this will protect yourself ( incase your maid play games), this will also protect future employer
2) look for a local ee, goggle it or look it up from BK here, i see many ee here are looking for jobs to take care bb, should be fine, install a webcam if you still worry
3) FIRE YOUR MAID ASAP!!
當鋪 must have cam la, if you report police, then police can ask the shop for the video.
but at the first place you may need to get the 'shop receipt' on hand to proof the maid has 'dong' your things.
Call police first & contact 當鋪, told them you had contract police already. Let's them to hold the golden until police to check. And ask the police/ 當鋪 to check the CAM record.
And contact agency to apply local maid immediately or local EE to take care BB for temp.
