Ninety percent of homicide cases were cracked within 24 hours and detection rates for robberies hit 100 percent for the first time in Beijing from January to June, said Beijing's public security bureau on Wednesday.

In the first half year, Beijing police solved a total of 33,000 criminal cases, with homicide case registration dropping by 22 percent and with a detection rate of 100 percent for five consecutive years, according to the press conference. From January to June, more than 26,000 suspects have been seized, an increase of 2.7 percent year-on-year. 

Eight types of felonies dropped by 18 percent, a new low in history, while the detection rate hit 83.3 percent, a record high. 

Robbery and fraud make up the majority of criminal cases at 41.6 percent and 36.3 percent respectively, according to the press conference.

Since house-breaking tends to evolve into burglaries, the police managed to lower the case registration rate of Beijing's house-breaking theft by 28.4 percent and increase the detection rate by 13.2 percent through prevention and crackdowns.

The number of registered vehicle thefts has been brought to under 100, a decrease of 23.1 percent year-on-year, a record low. 

More than 500 telecom fraud cases have been cracked, marking a 17 percent year-on-year increase. More than 1,000 telecom fraud suspects have been arrested, preventing losses of 760 million yuan ($108.6 million) for the public.

In March, the Beijing police established a laboratory with 14 high-tech companies across the country, developing and implementing intelligent, virtual reality and customized products for internet, traditional and occupational crimes. The move has enhanced the capital city's criminal investigation capability in cracking down on crimes.
