Boy in China loses sight in eye after playing with desiccant dry pack

Desiccant packs, which are usually made up of silica gel grains, absorb water and are used to help food remain dry.

The accident happened when after finishing his snack, the boy, Keke, saw a small bag (desiccant dry pack) inside the snack box and took it out. He put the small bag (desiccant dry pack) into a drink bottle that contained  his beverage, after which the bottle exploded.

According to a doctor, Keke's right eye had been dissolved by alkaline liquid erosion, resulting in permanent blindness in that eye.

Lesson to be learnt:
Parents must remember to remove any desiccant packs found in any snack boxes just in case they cause problems to your kids. They may be harmless, but can be dangerous if mixed with wrong liquid.

Scam warning: 120% jump in cases of fraudulent purchases charged to phone bills


The police have seen a sharp increase in the number of fraudulent purchases being charged to mobile phones, with 130 cases reported in the first 11 months of this year, up 120% from the same period last year.

The total amount cheated so far this year is at least S$16,000, the police added in a news release.

These scammers operated by initiating contact with the victims over Facebook and sometimes even created accounts closely resembling that of the victims' friends, the police said.

They would then ask for the victims' mobile phone number and mobile service provider and even phone PIN to buy online gaming credits or online gift cards using the victims' mobile phone numbers.

Precautions
The police has advised members of the public to take the following precautions to avoid falling prey to such scams:
  • Do not share personal information like OTP and verification codes with anyone
  • Be wary when accepting friend requests from people on social networking sites
  • If in doubt, verify with a friend if they have sent the request before accepting it
  • Report fraudulent charges on mobile phone bills immediately
