I have a friend who stole 900 yuan's cash in a hotel. He's in custody now. How long will he be detained? What kind of punishment will there be?

People's Republic of China (PRC) Public Security Administration Punishment Law

Article 49 Whoever steals, swindles, robs, robs, extorts or intentionally damages public or private property shall be detained for not less than five days but not more than ten days, and may also be fined not more than 500 yuan; If the circumstances are serious, he shall be detained for more than 10 and less than 15, and may also be fined less than 1000 yuan.

Your friend will be detained 15 days. Those who have a criminal record of theft within three years can be sentenced to reeducation through labor for more than six months and less than three years.
